Software I maintain or maintained

I maintain or have maintained various software (mostly but not all free software and open source software), detailed below. I have also contributed to many other pieces of free software. Unreleased software, and ad hoc programs (possibly released in places such as mailing lists, the On-Line Encyclopedia of Integer Sequences or in conjunction with publications listed on my publications page, but never maintained as a software package on an ongoing basis), are not covered here.

• Actively co-maintained and developed: GCC, glibc, GNU toolchain and C standards development.
• Active: matholymp, Python software for creating and maintaining websites for mathematical olympiads, with online registration and support for various associated administrative functions.
• Inactive since 2005, others may have newer versions: bsd-games, the GNU/Linux port of the NetBSD games collection.
• Inactive since 2004: nppt, an enhanced ppt(6) to draw pictures of punched paper tape in both ASCII and PostScript formats.
