pandoc/plugins/IncludeFilePlugin.hs
fiddlosopher 874c3e0dea Added a plugin system, based on hint.
+ In Text.Pandoc.Definition, added processIn, processInM,
  and queryIn, and deprecated processPandoc and queryPandoc
  for these more general functions, which are useful in writing
  plugins.

+ Added module Text.Pandoc.Plugins.

+ Added a --plugins option to Main, and code to run the parsed pandoc
  document through all the plugins.

+ Provided five sample plugin files in the plugins/ directory.

+ Documented --plugin in the pandoc man page and README.
