"""%(prog)s - generate information from built-in bzr help
20
%(prog)s creates a file with information on bzr in one of
21
several different output formats:
24
bash_completion bash completion script
29
python2.4 generated-docs.py man
30
python2.4 generated-docs.py bash_completion
32
Run "%(prog)s --help" for the option reference.
35
# Plan (devised by jblack and ndim 2005-12-10):
36
# * one generate_doc.py script in top level dir right beside bzr
37
# * one tools/doc_generate/ directory (python module)
38
# We did not put the stuff into bzrlib because we thought
39
# that all this stuff doesn't need to get loaded every time you run bzr.
40
# However, I'm not sure that is actually true (ndim 2005-12-11).
41
# * several generator scripts like
42
# tools/doc_generate/autodoc_man_page.py
43
# autodoc_docbook_xml.py
45
# autodoc_bash_completion.py
46
# autodoc_zsh_completion.py
47
# * scripts are called by running something like
48
# "python2.4 generated_docs.py --man-page" or
49
# "python2.4 generated_docs.py --bash-completion" or
50
# "pytohn2.4 generated_docs.py --all"
52
# * one test case which iterates through all gen_*.py scripts and
53
# tries to generate all the file types, checking that all generators
54
# work (we'll let bzrinfogen/__init__.py provide the list to walk through)
55
# * those generator scripts walk through the command and option data
56
# structures to extract the required information
57
# * the actual names are just prototypes and subject to change
