X-Debbugs-CC: slg <0x2d@disroot.org> Hi guix, In the context of ;, I looked at the source code of pycryptodome, version 3.10.1. It bundles some fonts, javascript, CSS, and libtomcrypt. That's not the version packaged in guix, but presumably version 3.9.9 has the same issues as well. More specifically, the following things are bundled: Doc/sphinx_rtd_theme/static/js/theme.js: Minified javascript code. It starts with /* sphinx_rtd_theme version 0.4.0 | MIT license */ Doc/sphinx_rtd_theme/static/js/modernizr.min.js: Likewise, and starts with /* Modernizr 2.6.2 (Custom Build) | MIT & BSD */ Doc/sphinx_rtd_theme/static/fonts: Various fonts (‘font awesome’, ‘roboto slab’, ‘lato’, ‘inconsolata’). Doc/sphinx_rtd_theme/static/css: Minified CSS. One file starts with /* sphinx_rtd_theme version 0.4.0 | MIT license */, the other is of unknon origin. There are also 'css.map' files. I don't know what these are. src/libtom: Bundled headers from 'libtomcrypt'. Curiously, I don't see corresponding '.c' files. Greetings, Maxime.
