   2 """
   3 Based on acronyms.py, tries a similar thing but without the
   4 carets surrounding the words to be expanded and supports
   5 optional URLs.  Definitions look like:
   6         entry :: this is a tool tip[| this is a url]
   7 
   8 Note that it does not use the formatter correctly. The rule is: do never nest calls to the formatter.

  10 Example:
  11 #FORMAT glossary
  12 #pragma glossary-definitions GlossaryDefs
