=head1 DESCRIPTION
This packages manages Automake's options and strictness settings.
Options can be either local or global. Local options are set using an
C variable in a F and apply only to
this F. Global options are set from the command line or
passed as an argument to C, they apply to all
Fs.

use vars '%_global_options'; # From AM_INIT_AUTOMAKE or the command line.
# Whether process_option_list has already been called for the current
# Makefile.am.

# Whether process_global_option_list has already been called.

Reset the options variables for the next F.
In other words, this gets rid of all local options in use by the
previous F.
