mgod
(ver. 1.0)
Freeware


mgod is a mini gopher server for inetd.  mgod can serve a 
directory structure, taking extra data from hidden files in
each directory (called .gopher).  It can invoke external 
scripts or executables for search string processing.


mgod should be a possible choice if you have a linux box and would like
to have your gopher server to be as minimal as the protocol itself
(single C, compiles to a 41K elf with -g on an amd64 system).
Runs from inetd. Some features:
  - dynamic content generation ("moles", but even parts of static menu
    files can be generated)
  - reverse and by mtime sort options (easy phlogging)
  - include mtime in menu descriptions option (easy phlogging)
  - support "include" command in control files
  - URL: link redirection
  - logging (can try to discover originating peer IP address from stdin
    socket)
  - no library dependencies (needs gcc and _GNU_SOURCE)
  - comes with a cgi app (also .c) that makes an easy HTTP gateway
    (with direct support for creating RSS feeds from menus)
