# Usage:
# ./autocompile.py path ext1,ext2,extn cmd
#
# Blocks monitoring |path| and its subdirectories for modifications on
# files ending with suffix |extk|. Run |cmd| each time a modification
# is detected. |cmd| is optional and defaults to 'make'.
#
# Example:
# ./autocompile.py /my-latex-document-dir .tex,.bib "make pdf"
#
# Dependencies:
# Linux, Python 2.6, Pyinotify
#
