THIRD-PARTY COMPONENTS

The following third-party works are redistributed with λWAVES under their own
licences.  Each licence file named below ships in the tree beside the work it
covers; nothing here is fetched from a third-party host at run time.

The three interface typefaces are SUBSET for this lab.  A subset is a Modified
Version under the SIL Open Font License, and each entry below says so.

1.  LW Title  —  the wordmark's typeface
    Derived from: Spinwerad 0.3 by gluk (gluksza@wp.pl)
    Licence:   SIL Open Font License, Version 1.1 (26 February 2007)
    Notice:    Copyright (c) 1997-2008, gluk (gluksza@wp.pl),
               with Reserved Font Names spinwerad
               (the author's licence file reads 1997-2008; the original font
               binary's own licence record reads "Copyright (c) 2009, gluk
               (gluksza@wp.pl), with Reserved Font Name spinwerad" — both are
               reproduced here.)
    Modified:  a five-glyph subset ("WAVES"), converted to WOFF2, and RENAMED
               per OFL §3, which forbids a Modified Version from using a
               Reserved Font Name.  Neither gluk nor the Spinwerad project
               produced or endorses this derivative.

2.  Roboto  —  the interface typeface
    Version:   3.015
    Licence:   SIL Open Font License, Version 1.1 (26 February 2007)
    Notice:    Copyright 2011 The Roboto Project Authors
               (https://github.com/googlefonts/roboto-classic)
               Roboto is a trademark of Google.
    Modified:  subset to the 198 characters this lab sets, variable axes kept,
               converted to WOFF2.  The Roboto licence declares no Reserved
               Font Name, so the subset keeps the name.

3.  STIX Two Math  —  the mathematical typeface
    Version:   2.0.2
    Licence:   SIL Open Font License, Version 1.1 (26 February 2007)
    Notice:    Copyright 2001-2021 The STIX Fonts Project Authors
               (https://github.com/stipub/stixfonts), with Reserved Font Name
               "TM Math".  STIX Fonts™ is a trademark of The Institute of
               Electrical and Electronics Engineers, Inc.
    Modified:  subset to the symbols this lab sets, converted to WOFF2.  The
               Reserved Font Name "TM Math" is not used, so OFL §3 permits the
               name.  This subset is not produced or endorsed by the STIX Fonts
               Project or by IEEE.

               GNU General Public License v3.0 only — the same author and licence as
               λWAVES, so no third-party obligation arises.  Taken by sha256

WITH THANKS

The people and works below informed λWAVES.  No code or asset of theirs is
redistributed here, so none of them places a licence obligation on this
tree — they are named because the lab would be poorer without them.
