| +"""Generate Google Mock classes from base classes.
|
| +
|
| +This program will read in a C++ source file and output the Google Mock
|
| +classes for the specified classes. If no class is specified, all
|
| +classes in the source file are emitted.
|

|
| +Usage:
|
| + gmock_class.py header-file.h [ClassName]...
|
| +
|
| +Output is sent to stdout.
