Apropos2 is a replacement for the GNU apropos command. It winnows down its responses when given more than one search word, unlike apropos which repeatedly prints everything that matches each word. Apropos2 is equivalent to "apropos word1 | grep -i word2 | ... | grep -i wordn", but with better error messages.
uWiki is a minimalistic wiki engine. All actions are implemented in external scripts. These scripts are wikified, and thus the wiki is extensible by itself. All dynamic access is protected through ACLs. Wiki content and Web content can be mixed in the same directory hierarchy. Markup engines and revision control are plugin-able. Currently, asciidoc as the markup engine and git as the revision control backend are provided. Subdirectories can form independent sub-wikis with own revision control. Features like distributed pages that syncronize between wikis, spam protection, and batch jobs to schedule mirroring of other content (bittorrent, git, rsync, and wget) are in planning.
process-getopt is a wrapper around getopt(1) for bash that allows a developer to define command line options with their descriptions through a single function call. These definitions are then used in runtime processing of command line options as well as in generating help and man pages. This results in more internal consistency in bash scripts, particularly when they are maintained and changed later. It also saves a little time in coding and producing nicely formatted documentation. It is quite similar to GNU's argp in glibc for compiled languages. Samples and a manual are included.
