Pygments allows you to beautify pieces of code to show in outside your Editor. This gist compiles some best practices.

pygmentize is best installed in a virtualenv so you need to activate before using it.

pigsplit splits the file every 45 lines (general good size for PPT) and reate multiple PNGs - it doesn't respect langage-based line breaks so be careful

pigrtf will format in RTF format and copy to the clipboard (on MAC) to paste directly into PowerPoint or Word

pig will create a png with some safe defauls

pygmentize -N file will try to guess the language formatter supported for this file
