      26  Config Files
      27  ============
      28  Configuration files can be specified with the C{--config} option.
      29  These files are read using U{ConfigParser
      30  <http://docs.python.org/lib/module-ConfigParser.html>}.  Configuration
      31  files may set options or add names of modules to document.  Option
      32  names are (usually) identical to the long names of command line
      33  options.  To specify names to document, use any of the following
      34  option names::
      35
      36    module modules value values object objects
      37
      38  A simple example of a config file is::
      39
      40    [epydoc]
      41    modules: sys, os, os.path, re, %(MYSANDBOXPATH)/utilities.py
      42    name: Example
      43    graph: classtree
      44    introspect: no
      45
      46  All ConfigParser interpolations are done using local values and the
      47  environment variables.
      48
      49
      50  Verbosity Levels
      51  ================
      52  The C{-v} and C{-q} options increase and decrease verbosity,
      53  respectively.  The default verbosity level is zero.  The verbosity
      54  levels are currently defined as follows::
      55
      56                  Progress    Markup warnings   Warnings   Errors
      57   -3               none            no             no        no
