	defplus - append to an existing macro

This is a filepp module which allows existing macros to be appended to.
It adds one keyword:
#defplus MACRO DEFINITION

The syntax of #defplus is the same as #define, only of MACRO already
exists, DEFINITION is appended to the existing definition for MACRO.

There is a simple test file included with this module.  To test the
defplus module use the following command (the file "test" is in this
directory):

filepp -m defplus.pm test.in

For full documentation on how to use filepp and the defplus module read
the filepp man page.
