A command line tool that can be used to syntax check configuration files. Not an extensive top to bottom configuration checker, just a tool for verifying syntax in a single file.

Do all %if have a corresponding %endif, are all parenthesis balanced, are all line endings proper windows CR-LF (just ran into this issue with a file in Unix line endings), list all unknown variables (allow extending the known variables so we can add in-house variables to the check). Are there any invisible unicode characters, etc...

Currently the only way to do this is open a file with the configuration. Being able to quickly check syntax would be a huge timesaver (many text editors can do this internally and show the output from a CLI tool).
