# Extract From Release/Patch Install Package

To extract the source from a release or patch install package, specify the data directory in the install package as the source directory. For example, the following invocation extracts source from a patch install package named `CM1.0_1` in the `C:\CMInstall` directory into `C:\CMExtract` and marks the extract as version `CM1.0_1`:

    			perl extractCMSource.plx -s C:\CMInstall\CM1.0_1\CMCCB\data
    			     -d C:\CMExtract -v CM1.0_1
