"""
Command-line interface for epydoc. Abbreviated Usage::
epydoc [options] NAMES...
NAMES... The Python modules to document.
--html Generate HTML output (default).
--latex Generate LaTeX output.
--pdf Generate pdf output, via LaTeX.
-o DIR, --output DIR The output directory.
--inheritance STYLE The format for showing inherited objects.
-V, --version Print the version of epydoc.
-h, --help Display a usage message.
Run \"epydoc --help\" for a complete option list. See the epydoc(1)
man page for more information.
Config Files
============
Configuration files can be specified with the C{--config} option.
These files are read using U{ConfigParser
<http://docs.python.org/lib/module-ConfigParser.html>}. Configuration
files may set options or add names of modules to document. Option
names are (usually) identical to the long names of command line
options. To specify names to document, use any of the following
option names::
module modules value values object objects
A simple example of a config file is::
[epydoc]
modules: sys, os, os.path, re, %(MYSANDBOXPATH)/utilities.py
name: Example
graph: classtree
introspect: no
All ConfigParser interpolations are done using local values and the
environment variables.
Verbosity Levels
================
The C{-v} and C{-q} options increase and decrease verbosity,
respectively. The default verbosity level is zero. The verbosity
levels are currently defined as follows::
Progress Markup warnings Warnings Errors
-3 none no no no
-2 none no no yes
-1 none no yes yes
0 (default) bar no yes yes
1 bar yes yes yes
2 list yes yes yes
