Command Line Syntax

GBRComp can be run by calling its various modules from a script or command line. This is a bit complicated but this section will show how to go about constructing a proper batch file.

Getting a Batch File Prototype

The GBRComp GUI generates a batch file each time GBRComp is run. The user can arrange to create just the batch file and to save it by making the correct choices in the Preference Settings dialog.

If Create Batch File is checked, GBRComp will not actually execute the engine but just produce a batch file.

If Keep is checked, GBRComp will keep a batch file that was used to launch the engine instead of erasing it during the cleanup of temporary files.

Below is a script generated by the GBRComp GUI and commented by hand. All comments begin with the # sign. Because the lines are so long, they have been broken for readability. A CRLF indicates that there is actually a carriage return line feed but CRLF is obviously not part of the batch file.
