manServer is a troff (or nroff) to HTML interpreter written in Perl. It is designed specifically to convert manual pages written using the man(7) troff macros into HTML for display and navigation with a Web browser. To this end it includes direct support for man macros (also limited support for tbl, eqn, and the doc macros) as well as the most common troff directives.
PhotoFrame is a PHP4 script that automatically creates a clean Web interface (using frames) from a directory full of JPEG, PNG and GIF images. It creates thumbnails automatically and will use JPEG comments if it finds them. 20 languages are supported, and images, captions, and comments can all be administered via the Web. No database or metafiles are needed.
masqidentd is an Ident daemon for Linux systems that use IP masquerading. It implements the recommendations in RFC1413. It also has the ability to forward Ident requests from a client to a machine sitting behind the masquerade service. Users also have the ability to override the default Ident response. This program is most useful for people who use IRC using mIRC or Pirch behind IP masquerade. masqidentd is intended for use with ipchains only.
Mercat is a light-weight, cross platform programming language. It is garbage collected and self hosting and produces portable byte-compiled binaries that can be executed on any platform with the appropriate interpreter. Interpreters are available for Linux, DOS (32-bit) and DOS (16-bit) and the interpreter source should be easily compilable for other platforms.
mess822 is a fast library for parsing Internet mail messages, with several qmail-compatible applications. It supports the full complexity of RFC 822 address lists and common RFC 822 extensions, and extracts each address as an easy-to-use string, with a separate string for the accompanying comment. mess822 also converts RFC 822 dates into libtai's struct caltime format, with support for numeric time zones, the standard old-fashioned time zones, and many nonstandard time zones.
MidiMountain is a sequencer to edit standard MIDI files. Its easy-to-use interface should help beginners to edit and create MIDI songs (sequences), and it is designed to edit every definition known to standard MIDI files and the MIDI transfer protocol, from easy piano roll editing to changing binary system exclusive messages.
Mod_auth_kerb is an Apache module designed to provide Kerberos user authentication to the Apache web server. Using the Basic Auth mechanism, it retrieves a username/password pair from the browser and checks them against a Kerberos server as set up by your particular organization. It also supports mutual ticket authentication, although most browsers do not support that natively.
mod_proxy_add_forward.c is an Apache module that adds a 'X-Forwarded-For' header to outgoing proxy requests like Squid does. You can then get the client IP back on the proxied host by setting r- >connection->remote_ip from this header. It's very useful for the common lightweight frontend/heavy backend mod_perl setup.
