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 synonyms.
The --rootdir option changes the programs idea of what "/" is when processing include directives. This is
useful when validating a configuration that is not installed on a target system yet.
