'''
Convert VMD plugin source files for PyMOL.
(Modified version of "contrib/uiuc/plugins/molfile_plugin/update.py")

Please download and unpack the VMD source code from:

  http://www.ks.uiuc.edu/Development/Download/download.cgi?PackageName=VMD

Then run this script from the PyMOL source root and point it to the "plugins"
directory from the VMD source tree. Example:

  cd /tmp
  tar xzf vmd-1.9.1.src.tar.gz
  cd /tmp/pymol
  python vmd_plugins_update.py /tmp/plugins

You can enable/disable particular plugins from the "src_list" variable in
this file.
