Xibit (tibix) - the image gallery generator for werc
Xibit can:
 - generate thumbnails from almost any picture format
 - generate preview images with captions
 - display them (rather brokenly for now)
 
 
 Dependencies:
  - Plan9port
  - Imagemagick
  - werc
 
 
 To make it work:
 1, clone the git repo at git://home.9souldier.org/xibit into $werc_root/apps
 2, pick a directory to serve the gallery from
 3, create an _werc and _werc/xibit directory in there, the xibit directory needs to be writable by the webserver to generate the thumbnails (at one point i'll probably make a cronjob, and then this will be optional)
 4, create an _werc/config file (readable by the webserver), that contains the options for xibit
 5, add xibit to the enabled_apps in initrc.local (or the local per-directory config file)
That should get you going.

to use captions just create a directory in GALLERY/_werc/xibit called captions, make it readable by the weberver and add the captions as files, using the following naming convention:
       image.imageextension.md
     the caption handler accepts markdown formatting

to enable comments add the comments handler (bridge) to the enabled apps, it'll (should) automatically work with xibit

Config options:
 - fmts:
   file extensions recognised
     ex. fmts=(jpg gif png svg)
 - thumbsize:
   size of thumbnails to generate, accepts 
     ex. thumbsize='140x'
 - previewsize:
   size of the previews to generate
     ex. previewsize='x460'

check_user:
   Enforce authentication
   This has been ripped out of the xibit code, if you want to enable perms enforcing, you should add the following to your config:
if ( ! check_user) {                #if fyou want to enforce per-group permissions, do "if( ! check_user $group) {"
   enabled_apps=()               #maybe you want to leave some apps on, i just do this on a per-directory besis
   handler_body_main=(echo '<a href="/_users/login">please log in</a>')
}
