=head1 NAME

openxpki-configure - Create OpenXPKI config files from meta-configuration.

=head1 USAGE 

openxpki-configure [OPTIONS]

  Options:
    --help         display this help text and exit
    --batch        non-interactive configuration
    --force        overwrite existing files
    --template     specify template (default: default)
    --createdirs   create missing directories
    --             args following -- are literally passed to openxpki-metaconf

This script generates the OpenXPKI configuration files from a set of
templates (taken from $TEMPLATEDIR)
by filling in values specified in the OpenXPKI meta configuration
$OPENXPKICONFDIR/openxpki.conf.

Please note that this meta configuration is intended for getting
OpenXPKI up and running quickly. Beyond basic configuration there 
are many configuration parameters that cannot be set by this approach.

(For a more advanced setup may be advisable to modify the settings in
OpenXPKI's XML configuration files directly and NOT use openxpki-configure.)
