dnl default is one of:

dnl most -- disabled by default. enabled explicitly or with most or all.
dnl static -- enabled as static by default, must be explicitly changed.

dnl XXX: The arg must really be empty here. Passing an empty shell
dnl XXX: variable doesn't work for some reason. This should be
dnl XXX: fixed.
dnl
dnl basically: yes/no is a hard setting. "most" means follow the "most"
dnl setting. otherwise, fall under the "all" setting.
dnl explicit yes/no always overrides, except if the user selects
dnl "reallyall".
dnl
dnl prereq_module is a module (without the "mod_" prefix) that must be enabled
dnl if the current module is enabled. If the current module is built
dnl statically, prereq_module must be built statically, too. If these
dnl conditions are not fulfilled, configure will abort if the current module
dnl has been enabled explicitly. Otherwise, configure will disable the
dnl current module.
dnl prereq_module's APACHE_MODULE() statement must have been processed
dnl before the current APACHE_MODULE() statement.
