To disable searching for configuration files, pass C<--no-config>.

You can put multiple profiles in a single file by using section names like C<[profile=SOMENAME]> or C<[SOMESECTION profile=SOMENAME]>. Those sections will only be read if you specify the matching C<--config-profile SOMENAME>.

You can also put configuration for multiple programs inside a single file, and use filter C<program=NAME> in section names, e.g. C<[program=NAME ...]> or C<[SOMESECTION program=NAME]>. The section will then only be used when the reading program match...

Finally, you can filter a section by environment variable using the filter C<env=CONDITION> in section names. For example if you only want a section to be read if a certain environment variable is true: C<[env=SOMEVAR ...]> or C<[SOMESECTION env=SOME...

List of available configuration parameters:

 escaped_string (see --escaped-string)
 format (see --format)
 naked_res (see --naked-res)
 string (see --string)
 template (see --template)
