"""bzr-infogen.py - generate information from built-in bzr help
bzr-infogen.py creates a file with information on bzr in one of
several different output formats:
man man page
bash_completion bash completion script
...
Run "bzr-infogen.py --help" for usage information.
"""
# Plan (devised by jblack and ndim 2005-12-10):
# * one bzr-infogen.py script in top level dir right beside bzr
# * one bzrinfogen/ directory (python module)
# We did not put the stuff into bzrlib/infogen/ because we thought
# that all this stuff doesn't need to get loaded every time you run bzr.
# However, I'm not sure that is actually true (ndim 2005-12-11).
# * several generator scripts like
# bzrinfogen/gen_man_page.py
# gen_docbook_xml.py
# gen_html.py
# gen_bash_completion.py
# gen_zsh_completion.py
# * scripts are called by running something like
# "bzr-infogen.py --man-page" or "bzr-infogen.py --bash-completion"
# * one test case which iterates through all gen_*.py scripts and
# tries to generate all the file types, checking that all generators
# work (we'll let bzrinfogen/__init__.py provide the list to walk through)
# * those generator scripts walk through the command and option data
# structures to extract the required information
# * the actual names are just prototypes and subject to change
