+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>')
+}
