Buffy displays a window with a summary of your mailboxes and lets you open them in your mail program. It is written with the intent of being a handy everyday tool for people working with large volumes of mail. For mutt users, it can be a nice front-end to supplement the simple built-in folder browser when one has many folders to keep track of. It tries hard to work out of the box and looks for mail folders in sensible places and comes with reasonable defaults. It supports mail stored in maildir, mbox, and gzipped mbox format.
cgi_trampoline.c is a parametric C program which executes a CGI script in a specific directory and sets the real UID and GID to the effective UID and GID. It is safe to set the setuid/setgid bits of the binary of cgi_trampoline.c. initgroups() and setgroups() are not called, because this works only as root. cgi_trampoline.c contains optimizations for Linux i386, so the generated binary will be statically linked and very small.
LibJAD is collection of miscellaneous routines for a variety of purposes. This library includes functions of reading ini style files, multi-threaded programming, finding the number of processors available on the system, computing combinations and permutations, base64 and URL encoding, and working with ASN1 and PGM files.
layout is a tcl package that allows you to create layouts simply and efficently. The layout you want is "written" in a variable that is parsed by proc "layout", which will arrange for normal managers (grid and pack) to handle it. Since the variable can be dynamically created, the layout can be created on the fly. The format of the variable is intuitive so that reading the code is easy, and change in the layout can be done in seconds. Comes with a detailed demo.
