This program reads the given ipsec.conf style configuration file, interpreting the also= options, and outputs an equivalent ipsec.conf file. The purpose of this program is to validate the input processing. This can also be used to validate the syntax of a configuration file.
The options --debug and --verbose are currently synonums.
The --rootdir option changes the programs idea of what "/" is when processing include directives. This is useful when validating a configuration which is not installed on a target system yet.
