"""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.
