The __CONFIG directive and all of the configuration options are describe
in the MPASM user's guide. Recall that gpasm is an open source
implementation of MPASM. You may also wish to read about the configuration
bits in the data sheet on the 16f877. In addition, you can look at the
'F877 include file to see how all of these components are defined. I
suppose it was only fortuitous that gpsim had an 'obvious' example of the
__CONFIG.
