"""
This program runs gcc/g++ on a cpp/c source file. It supposed to be used in
SciTE in a portable way. A bash script can do what it does. The same can't
be said for a .bat file.
    + It's able to handle sourcefiles with spaces in them
    + Runs the appropriate compiler depending on the extension of the files
    + Generates the right executable name irregardless of the position of
      the '-o' option.
