RecipePacker:
Packs all python source files from current directory into a single recipe file
that can be later run to recreate packed files.
Usage:
Copy RecipePacker module into source directory.
Run RecipePacker module.
- Creates _recipe directory and writes _recipe.py to _recipe directory.
Run _recipe.py.
- Recreates packed files into containing directory.
Notes:
* Skips files whose names begin with underscore or contain "recipe".
* Hasn't been checked with unicode.
