 """Extract a session from the IPython input history.
 
 Usage:
   ipython-get-history.py sessionnumber [outputfile]
 
 If outputfile is not given, the relevant history is written to stdout. If
 outputfile has a .py extension, the translated history (without IPython's
 special syntax) will be extracted.
 
 Example:
   ./ipython-get-history.py 57 record.ipy
 
 
 This script is a simple demonstration of HistoryAccessor. It should be possible
 to build much more flexible and powerful tools to browse and pull from the
 history database.
