# Where SOURCE-FILES is the list of source files to extract init functions from.

# An initialization function is introduced using the "INIT_GDB_FILE"
# macro. In ordinary code this expands to a function declaration (to
# avoid a warning) and then the start of a definition. In the
# generated init.c, though, it is expanded differently. For example:
#
# INIT_GDB_FILE (foo)
# {
# ...
# }
#
# Abort on command error.
