+# Kerbal Space Program Configuration Syntax
 
-This is a `.tmLanguage` specification for configuration files in [Kerbal Space Program](https://kerbalspaceprogram.com/), including `persistent.sfs` and `part.cfg` files. I developed this for syntax highlighting when editing these files in [Sublime Text](http://www.sublimetext.com/). I'm also trying to support ModuleManager syntax.

-`KSP configuration.JSON-tmLanguage` is the JSON "source" for the specification, which can be "compiled" into the XML `.tmLanguage` type with [AAAPackageDev](https://github.com/SublimeText/AAAPackageDev). All the work is done in the JSON.

-I am quite new to regex so I welcome suggestions. It's far from complete.
