 Import Text

 Copyright 2005 by Waylan Limberg (http://achinghead.com)

 This script pulls all the text files (.txt) 
 from a given directory and converts them to
 the proper format for PMWiki pages.
 Intended to be called from the command line.

 params: source/dir/ (required), destination/dir/ (optional), GroupName (optional)
 Usage: php.exe -f importToWiki.php /path/to/source/dir/ /path/to/destination/dir/ Groupname
 Notes: * each dir given as arg must contain an ending slash ('/')
        * When a Group name is provided it is appended to begining of filename:
          (ie. file.txt becomes Groupname.File - note case change of first char)
 Warning: This will overwrite existing files without confirming!
