   where such license applies only to those patent claims licensable
   by such Contributor that are necessarily infringed by their
   Contribution(s) alone or by combination of their Contribution(s)
   with the Work to which such Contribution(s) was submitted. If You
   institute patent litigation against any entity (including a
   cross-claim or counterclaim in a lawsuit) alleging that the Work

       the Derivative Works; and

   (d) If the Work includes a "NOTICE" text file as part of its
       distribution, then any Derivative Works that You distribute must
       include a readable copy of the attribution notices contained
       within such NOTICE file, excluding those notices that do not
       pertain to any part of the Derivative Works, in at least one
       of the following places: within a NOTICE text file distributed
       as part of the Derivative Works; within the Source form or
       documentation, if provided along with the Derivative Works; or,
       within a display generated by the Derivative Works, if and
       wherever such third-party notices normally appear. The contents
       of the NOTICE file are for informational purposes only and
       do not modify the License. You may add Your own attribution
       notices within Derivative Works that You distribute, alongside
       or as an addendum to the NOTICE text from the Work, provided
       that such additional attribution notices cannot be construed
       as modifying the License.

   Contributor provides its Contributions) on an "AS IS" BASIS,
   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
   implied, including, without limitation, any warranties or conditions
   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
   PARTICULAR PURPOSE. You are solely responsible for determining the
   appropriateness of using or redistributing the Work and assume any
   risks associated with Your exercise of permissions under this License.

8. Limitation of Liability. In no event and under no legal theory,
   whether in tort (including negligence), contract, or otherwise,
   unless required by applicable law (such as deliberate and grossly
   negligent acts) or agreed to in writing, shall any Contributor be
   liable to You for damages, including any direct, indirect, special,
   incidental, or consequential damages of any character arising as a
   result of this License or out of the use or inability to use the
   Work (including but not limited to damages for loss of goodwill,
   work stoppage, computer failure or malfunction, or any and all
   other commercial damages or losses), even if such Contributor
   has been advised of the possibility of such damages.

   the Work or Derivative Works thereof, You may choose to offer,
   and charge a fee for, acceptance of support, warranty, indemnity,
   or other liability obligations and/or rights consistent with this
   License. However, in accepting such obligations, You may act only
   on Your own behalf and on Your sole responsibility, not on behalf
   of any other Contributor, and only if You agree to indemnify,
   defend, and hold each Contributor harmless for any liability
   incurred by, or claims asserted against, such Contributor by reason
   of your accepting any such warranty or additional liability.

📋 Original OFL 1.1 License Text
PREAMBLE

The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative
font projects, to support the font creation efforts of academic and linguistic communities, and
to provide a free and open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long
as they are not sold by themselves. The fonts, including any derivative works, can be bundled,
embedded, redistributed and/or sold with any software provided that any reserved names are not
used by derivative works. The fonts and derivatives, however, cannot be released under any other
type of license. The requirement for fonts to remain under this license does not apply to any
document created using the fonts or their derivatives. DEFINITIONS

“Font Software” refers to the set of files released by the Copyright Holder(s) under this
license and clearly marked as such. This may include source files, build scripts and
documentation.

“Reserved Font Name” refers to any names specified as such after the copyright statement(s).

“Original Version” refers to the collection of Font Software components as distributed by the
Copyright Holder(s).

“Modified Version” refers to any derivative made by adding to, deleting, or substituting – in
part or in whole – any of the components of the Original Version, by changing formats or by
porting the Font Software to a new environment.

“Author” refers to any designer, engineer, programmer, technical writer or other person who
contributed to the Font Software. PERMISSION & CONDITIONS

Permission is hereby granted, free of charge, to any person obtaining a copy of the Font
Software, to use, study, copy, merge, embed, modify, redistribute, and sell modified and
unmodified copies of the Font Software, subject to the following conditions:

1) Neither the Font Software nor any of its individual components, in Original or Modified
Versions, may be sold by itself.

2) Original or Modified Versions of the Font Software may be bundled, redistributed and/or sold
with any software, provided that each copy contains the above copyright notice and this license.
These can be included either as stand-alone text files, human-readable headers or in the
appropriate machine-readable metadata fields within text or binary files as long as those fields
can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font Name(s) unless explicit
written permission is granted by the corresponding Copyright Holder. This restriction only
applies to the primary font name as presented to the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font Software shall not be
used to promote, endorse or advertise any Modified Version, except to acknowledge the
contribution(s) of the Copyright Holder(s) and the Author(s) or with their explicit written
permission.

5) The Font Software, modified or unmodified, in part or in whole, must be distributed entirely
under this license, and must not be distributed under any other license. The requirement for
fonts to remain under this license does not apply to any document created using the Font
Software.

TERMINATION

This license becomes null and void if any of the above conditions are not met.

DISCLAIMER

THE FONT SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED,

UBUNTU FONT LICENCE Version 1.0

PREAMBLE
This licence allows the licensed fonts to be used, studied, modified and
redistributed freely. The fonts, including any derivative works, can be
bundled, embedded, and redistributed provided the terms of this licence
are met. The fonts and derivatives, however, cannot be released under
any other licence. The requirement for fonts to remain under this
licence does not require any document created using the fonts or their
derivatives to be published under this licence, as long as the primary
purpose of the document is not to be a vehicle for the distribution of
the fonts.

DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this licence and clearly marked as such. This may
include source files, build scripts and documentation.

"Original Version" refers to the collection of Font Software components
as received under this licence.

"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to
a new environment.

"Copyright Holder(s)" refers to all individuals and companies who have a
copyright ownership of the Font Software.

"Substantially Changed" refers to Modified Versions which can be easily
identified as dissimilar to the Font Software by users of the Font
Software comparing the Original Version with the Modified Version.

To "Propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification and with or without charging
a redistribution fee), making available to the public, and in some
countries other activities as well.

PERMISSION & CONDITIONS
This licence does not grant any rights under trademark law and all such
rights are reserved.

Permission is hereby granted, free of charge, to any person obtaining a
copy of the Font Software, to propagate the Font Software, subject to
the below conditions:

1) Each copy of the Font Software must contain the above copyright
notice and this licence. These can be included either as stand-alone
text files, human-readable headers or in the appropriate machine-
readable metadata fields within text or binary files as long as those
fields can be easily viewed by the user.

2) The font name complies with the following:
(a) The Original Version must retain its name, unmodified.
(b) Modified Versions which are Substantially Changed must be renamed to
avoid use of the name of the Original Version or similar names entirely.
(c) Modified Versions which are not Substantially Changed must be
renamed to both (i) retain the name of the Original Version and (ii) add
additional naming elements to distinguish the Modified Version from the
Original Version. The name of such Modified Versions must be the name of
the Original Version, with "derivative X" where X represents the name of
the new work, appended to that name.

3) The name(s) of the Copyright Holder(s) and any contributor to the
Font Software shall not be used to promote, endorse or advertise any
Modified Version, except (i) as required by this licence, (ii) to
acknowledge the contribution(s) of the Copyright Holder(s) or (iii) with
their explicit written permission.

4) The Font Software, modified or unmodified, in part or in whole, must
be distributed entirely under this licence, and must not be distributed
under any other licence. The requirement for fonts to remain under this
licence does not affect any document created using the Font Software,
except any version of the Font Software extracted from a document
created using the Font Software may only be distributed under this
licence.

TERMINATION
This licence becomes null and void if any of the above conditions are
not met.

DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF

CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE LEGAL SERVICES. DISTRIBUTION
OF THIS DOCUMENT DOES NOT CREATE AN ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE USE OF THIS
DOCUMENT OR THE INFORMATION OR WORKS PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES
RESULTING FROM THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED HEREUNDER.

Statement of Purpose The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s)
(each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").

Certain owners wish to permanently relinquish those rights to a Work for the purpose of
contributing to a commons of creative, cultural and scientific works ("Commons") that the public
can reliably and without fear of later claims of infringement build upon, modify, incorporate in
other works, reuse and redistribute as freely as possible in any form whatsoever and for any
purposes, including without limitation commercial purposes. These owners may contribute to the
Commons to promote the ideal of a free culture and the further production of creative, cultural
and scientific works, or to gain reputation or greater distribution for their Work in part
through the use and efforts of others.

For these and/or other purposes and motivations, and without any expectation of additional
consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the
extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge
of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect
of CC0 on those rights.

1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright
   and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related
   Rights include, but are not limited to, the following: i.the right to reproduce, adapt,
   distribute, perform, display, communicate, and translate a Work; ii. moral rights retained by
   the original author(s) and/or performer(s); iii.publicity and privacy rights pertaining to a
   person's image or likeness depicted in a Work; iv.rights protecting against unfair
   competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
   v.rights protecting the extraction, dissemination, use and reuse of data in a Work;
   vi.database rights (such as those arising under Directive 96/9/EC of the European Parliament
   and of the Council of 11 March 1996 on the legal protection of databases, and under any
   national implementation thereof, including any amended or successor version of such
   directive); and vii.other similar, equivalent or corresponding rights throughout the world
   based on applicable law or treaty, and any national implementations thereof.

2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law,
   Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives,
   abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims
   and causes of action, whether now known or unknown (including existing as well as future
   claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the
   maximum duration provided by applicable law or treaty (including future time extensions),
   (iii) in any current or future medium and for any number of copies, and (iv) for any purpose
   whatsoever, including without limitation commercial, advertising or promotional purposes (the
   "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large
   and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver
   shall not be subject to revocation, rescission, cancellation, termination, or any other legal
   or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated
   by Affirmer's express Statement of Purpose.

3. Public License Fallback. Should any part of the Waiver for any reason be judged legally
   invalid or ineffective under applicable law, then the Waiver shall be preserved to the
   maximum extent permitted taking into account Affirmer's express Statement of Purpose. In
   addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected
   person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and

   (including future time extensions), (iii) in any current or future medium and for any number
   of copies, and (iv) for any purpose whatsoever, including without limitation commercial,
   advertising or promotional purposes (the "License"). The License shall be deemed effective as
   of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any
   reason be judged legally invalid or ineffective under applicable law, such partial invalidity
   or ineffectiveness shall not invalidate the remainder of the License, and in such case
   Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining
   Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of
   action with respect to the Work, in either case contrary to Affirmer's express Statement of

These libraries were built and linked to the final version of MetriCal incidentally through the use of GCC for some of our dependencies (CHOLMOD, OpenCV).

📋 Original GPL with Section 7 GCC Exception License
This is the Debian GNU/Linux prepackaged version of the GNU compiler
collection, containing Ada, C, C++, D, Fortran 95, Go, Objective-C,
Objective-C++, and Modula-2 compilers, documentation, and support
libraries.  In addition, Debian provides the gm2 compiler, either in
the same source package, or built from a separate same source package.
Packaging is done by the Debian GCC Maintainers
<debian-gcc@lists.debian.org>, with sources obtained from:

  ftp://gcc.gnu.org/pub/gcc/releases/  (for full releases)
  svn://gcc.gnu.org/svn/gcc/           (for prereleases)
  ftp://sourceware.org/pub/newlib/     (for newlib)
  git://git.savannah.gnu.org/gm2.git   (for Modula-2)

The current gcc-12 source package is taken from the git gcc-12-branch.

Changes: See changelog.Debian.gz

Debian splits the GNU Compiler Collection into packages for each language,
library, and documentation as follows:

Language       Compiler package  Library package    Documentation
---------------------------------------------------------------------------
Ada            gnat-12          libgnat-12          gnat-12-doc
C              gcc-12                              gcc-12-doc
C++            g++-12           libstdc++6         libstdc++6-12-doc
D              gdc-12
Fortran 95     gfortran-12      libgfortran5       gfortran-12-doc
Go             gccgo-12         libgo0
Objective C    gobjc-12         libobjc4
Objective C++  gobjc++-12
Modula-2       gm2-12           libgm2

For some language run-time libraries, Debian provides source files,
development files, debugging symbols and libraries containing position-
independent code in separate packages:

Language  Sources      Development   Debugging            Position-Independent
------------------------------------------------------------------------------
C++                                  libstdc++6-12-dbg  libstdc++6-12-pic
D         libphobos-12-dev

Additional packages include:

All languages:
libgcc1, libgcc2, libgcc4       GCC intrinsics (platform-dependent)
gcc-12-base                    Base files common to all compilers
gcc-12-soft-float              Software floating point (ARM only)
gcc-12-source                  The sources with patches

Ada:
libgnat-util12-dev, libgnat-util12   GNAT version library

C:
cpp-12, cpp-12-doc            GNU C Preprocessor
libssp0-dev, libssp0            GCC stack smashing protection library
libquadmath0                    Math routines for the __float128 type
fixincludes                     Fix non-ANSI header files

C, C++ and Fortran 95:
libgomp1-dev, libgomp1		GCC OpenMP (GOMP) support library
libitm1-dev, libitm1		GNU Transactional Memory Library

Biarch support: On some 64-bit platforms which can also run 32-bit code,
Debian provides additional packages containing 32-bit versions of some
libraries.  These packages have names beginning with 'lib32' instead of
'lib', for example lib32stdc++6.  Similarly, on some 32-bit platforms which
can also run 64-bit code, Debian provides additional packages with names
beginning with 'lib64' instead of 'lib'.  These packages contain 64-bit
versions of the libraries.  (At this time, not all platforms and not all
libraries support biarch.)  The license terms for these lib32 or lib64
packages are identical to the ones for the lib packages.

GCC RUNTIME LIBRARY EXCEPTION

Version 3.1, 31 March 2009

Copyright (C) 2009 Free Software Foundation, Inc. <http://fsf.org/>

Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.

This GCC Runtime Library Exception ("Exception") is an additional
permission under section 7 of the GNU General Public License, version
3 ("GPLv3"). It applies to a given file (the "Runtime Library") that
bears a notice placed by the copyright holder of the file stating that
the file is governed by GPLv3 along with this Exception.

When you use GCC to compile a program, GCC may combine portions of
certain GCC header files and runtime libraries with the compiled
program. The purpose of this Exception is to allow compilation of
non-GPL (including proprietary) programs to use, in this way, the
header files and runtime libraries covered by this Exception.

0. Definitions.

A file is an "Independent Module" if it either requires the Runtime
Library for execution after a Compilation Process, or makes use of an
interface provided by the Runtime Library, but is not otherwise based
on the Runtime Library.

"GCC" means a version of the GNU Compiler Collection, with or without
modifications, governed by version 3 (or a specified later version) of
the GNU General Public License (GPL) with the option of using any
subsequent versions published by the FSF.

"GPL-compatible Software" is software whose conditions of propagation,
modification and use would permit combination with GCC in accord with
the license of GCC.

"Target Code" refers to output from any compiler for a real or virtual
target processor architecture, in executable form or suitable for
input to an assembler, loader, linker and/or execution
phase. Notwithstanding that, Target Code does not include data in any
format that is used as a compiler intermediate representation, or used
for producing a compiler intermediate representation.

The "Compilation Process" transforms code entirely represented in
non-intermediate languages designed for human-written code, and/or in
Java Virtual Machine byte code, into Target Code. Thus, for example,
use of source code generators and preprocessors need not be considered
part of the Compilation Process, since the Compilation Process can be
understood as starting with the output of the generators or
preprocessors.

A Compilation Process is "Eligible" if it is done using GCC, alone or
with other GPL-compatible software, or if it is done without using any
work based on GCC. For example, using non-GPL-compatible Software to
optimize any GCC intermediate representations would not qualify as an
Eligible Compilation Process.

1. Grant of Additional Permission.

You have permission to propagate a work of Target Code formed by
combining the Runtime Library with Independent Modules, even if such
propagation would otherwise violate the terms of GPLv3, provided that
all Target Code was generated by Eligible Compilation Processes. You
may then convey such a combination under terms of your choice,
consistent with the licensing of the Independent Modules.

2. No Weakening of GCC Copyleft.

The availability of this Exception does not imply any general
presumption that third-party software is unaffected by the copyleft
requirements of the license of GCC.

hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform,
sublicense, and distribute the Work and such Derivative Works in Source or Object form.

3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor
hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made, use, offer to sell, sell,
import, and otherwise transfer the Work, where such license applies only to those patent claims
licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or
by combination of their Contribution(s) with the Work to which such Contribution(s) was
submitted. If You institute patent litigation against any entity (including a cross-claim or
counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work
constitutes direct or contributory patent infringement, then any patent licenses granted to You
under this License for that Work shall terminate as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof
in any medium, with or without modifications, and in Source or Object form, provided that You
meet the following conditions:

    (a) You must give any other recipients of the Work or Derivative Works a copy of this License;
    and

    (b) You must cause any modified files to carry prominent notices stating that You changed the
    files; and

    (c) You must retain, in the Source form of any Derivative Works that You distribute, all
    copyright, patent, trademark, and attribution notices from the Source form of the Work,
    excluding those notices that do not pertain to any part of the Derivative Works; and

    (d) If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative
    Works that You distribute must include a readable copy of the attribution notices contained
    within such NOTICE file, excluding those notices that do not pertain to any part of the
    Derivative Works, in at least one of the following places: within a NOTICE text file distributed
    as part of the Derivative Works; within the Source form or documentation, if provided along with
    the Derivative Works; or, within a display generated by the Derivative Works, if and wherever
    such third-party notices normally appear. The contents of the NOTICE file are for informational
    purposes only and do not modify the License. You may add Your own attribution notices within
    Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the
    Work, provided that such additional attribution notices cannot be construed as modifying the
    License.

    You may add Your own copyright statement to Your modifications and may provide additional or
    different license terms and conditions for use, reproduction, or distribution of Your
    modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and
    distribution of the Work otherwise complies with the conditions stated in this License.

5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution
intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms
and conditions of this License, without any additional terms or conditions. Notwithstanding the
above, nothing herein shall supersede or modify the terms of any separate license agreement you
may have executed with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade names, trademarks, service
marks, or product names of the Licensor, except as required for reasonable and customary use in
describing the origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor
provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT
WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation,
any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or
redistributing the Work and assume any risks associated with Your exercise of permissions under
this License.

8. Limitation of Liability. In no event and under no legal theory, whether in tort (including
negligence), contract, or otherwise, unless required by applicable law (such as deliberate and
grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for
damages, including any direct, indirect, special, incidental, or consequential damages of any
character arising as a result of this License or out of the use or inability to use the Work
(including but not limited to damages for loss of goodwill, work stoppage, computer failure or
malfunction, or any and all other commercial damages or losses), even if such Contributor has
been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works
thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty,
indemnity, or other liability obligations and/or rights consistent with this License. However, in
accepting such obligations, You may act only on Your own behalf and on Your sole responsibility,
not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each
Contributor harmless for any liability incurred by, or claims asserted against, such Contributor
by reason of your accepting any such warranty or additional liability.

    within a display generated by the Derivative Works, if and
    wherever such third-party notices normally appear. The contents
    of the NOTICE file are for informational purposes only and
    do not modify the License. You may add Your own attribution
    notices within Derivative Works that You distribute, alongside
    or as an addendum to the NOTICE text from the Work, provided
    that such additional attribution notices cannot be construed
    as modifying the License.

You may add Your own copyright statement to Your modifications and

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
