mac_alias lets you generate or read binary Alias and Bookmark records from Python code.
While it is written in pure Python, some OS X specific code is required to generate a proper Alias or Bookmark record for a given file, so this module currently is not portable to other platforms.
Credit is due to Wim Lewis <wiml@hhhh.org>, whose work on reverse engineering the alias format was extremely useful in writing this code. Alastair Houghton <alastair@alastairs-place.net> was responsible for reverse engineering the bookmark format.
