   3 = AgelSrc.py =
   4   Simple source code highlighting parser.
   5 
   6 == Install ==
   7  1. `$ easy_install Pygments`
   8   This parser uses highlighting facility of Pygments library.
   9   Thanks to [http://pygments.pocoo.org/docs/authors/ authors].
  10   So you must install this great library with EasyInstall (or install manually)
  11  2. download and install `AgelSrc.py` file to your `wiki/data/plugin/parser/`.
  12   You may need to restart your MoinMoin processes. (Recommended)
  13  3. Enjoy! :-)
  14 
  15 == Usage ==
  16  {{{#!AgelSrc filetype=python
  17  print 'hello, world!'
  18  }}}
  19 
  20  ...or...
  21 
  22  {{{#!AgelSrc
  23  #!/usr/bin/env python
  24  print 'hello, world!'
  25  }}}
  26 
  27  Second method may can fail if you didn't supply enough information for
  28  Pygments to //guess// syntax for your source code. (use 1st usage.)
