"""
Gexync is a GEX ini file editor.
The editor loads the INI file through the communication interface
without having to mount the virtual filesystem, which is unreliable
on some systems.
This utility allows live editing of the UNITS.INI file.
On save, a new version is loaded with formatting and error messages
generated by GEX, as if the virtual config filesystem was re-mounted.
The editor does not keep GEX claimed, instead does so only when needed.
This allows testing of the current configuration without having to close
and reopen the editor.
