The following options select definitions, templates and scheme functions
to use:

  Flg Arg Option-Name    Description
   -L Str templ-dirs     Search for templates in DIR

The following options modify how output is handled:

  Flg Arg Option-Name    Description
   -b Str base-name      Specify NAME as the base name for output
                                - may not be preset

      no  writable       Allow output files to be writable
                                - disabled as '--not-writable'

The following options are often useful while debugging new templates:

                                  -1 exactly, or

   -t Num timeout        Limit server shell operations to SECONDS
                                - it must be in the range:

These options can be used to control what gets processed in the

   -s Str skip-suffix    Skip the file with this SUFFIX
                                - prohibits the option 'select-suffix'

                                - may appear multiple times
   -U Str undefine       definition list removal pattern
                                - an alternate for 'define'

This option is used to automate dependency tracking:

  Flg Arg Option-Name    Description
   -M opt make-dep       emit make dependency file
                                - may not be preset
                                - may appear multiple times

help, version and option handling:

  Flg Arg Option-Name    Description
   -R Str reset-option   reset an option's state
   -v opt version        output version information and exit
   -? no  help           display extended usage information and exit
   -! no  more-help      extended usage information passed thru pager
   -u no  usage          abbreviated usage to stdout
   -> opt save-opts      save the option state to a config file

Options are specified by doubled hyphens and their name or by a single
hyphen and the flag character.
AutoGen creates text files from templates using external definitions.

The following option preset mechanisms are supported:
 - reading file $HOME
 - reading file ./.autogenrc
 - examining environment variables named AUTOGEN_*

The valid "trace" option keywords are:
  nothing       debug-message server-shell  templates     block-macros
  expressions   everything
  or an integer from 0 through 6
AutoGen is a tool designed for generating program files that contain
repetitive text with varied substitutions.
