r"""GerbMerge is a program that combines several Gerber
(i.e., RS274-X) and Excellon files into a single set
of files. This program is useful for combining multiple
printed circuit board layout files into a single job.

To run the program, invoke the Python interpreter on the
gerbmerge.py file. On Windows, if you installed GerbMerge in
C:/Python24, for example, open a command window (DOS box)
and type:
    C:/Python24/gerbmerge.bat

For more details on installation or running GerbMerge, see the
URL below.
