# This script parses remote_protocol.x or qemu_protocol.x and produces lots of
|
|
# boilerplate code for both ends of the remote connection.
|
|
#
|
|
# The first non-option argument specifies the prefix to be searched for, and
|
|
# output to, the boilerplate code. The second non-option argument is the
|
|
# file you want to operate on. For instance, to generate the dispatch table
|
|
# for both remote_protocol.x and qemu_protocol.x, you would run the
|
|
# following:
|
|
#
|
|
# remote_generator.pl -c -t remote ../src/remote/remote_protocol.x
|
|
# remote_generator.pl -t qemu ../src/remote/qemu_protocol.x
