# Source files are divided up along several axes:
#
# C vs. C++ - this is used on Windows to generated lists of object files
# with .c=.obj or .cpp=.obj
#
# Register vs. non-register - register files are scanned for registration
# functions, non-register files aren't.
#
# Flex-generated, Lemon-generated, and non-generated:
#
# we distribute non-generated files, as they're part of the source,
# and distribute Flex-generated files, as we don't require that
# people have Flex installed and don't distribute it ourself and
# thus can't guarantee that we can run Flex in the build process,
# but we don't distribute Lemon-generated files, as we distribute
# Lemon and can run it in the build process;
#
# "make maintainer-clean" on UN*X remove all generated files;
#
# "make distclean" on UN*X removes Lemon-generated files, as they're
# not in the distribution, but not Flex-generated files, as they
# are in the distribution;
#
# "make distclean" on Windows removes both Lemon-generated and
# Flex-generated files, as the Flex-generated files in the
# distribution were generated by Flex on UN*X, and won't compile
# on Windows;
#
# Flex-generated files can't be built with full warnings
# turned on, and can't be run through the checkAPI scripts,
# as they generate code that won't pass (we've tweaked
# Lemon to generate code that will pass).

# Build plugin.c, which contains the plugin_version[] string, a
# function plugin_register() that calls the register routines for all
# protocols, and a function plugin_reg_handoff() that calls the handoff
# registration routines for all protocols.
#
# We do this by scanning sources. If that turns out to be too slow,
# maybe we could just require every .o file to have an register routine
# of a given name (packet-aarp.o -> proto_register_aarp, etc.).
#
# Formatting conventions: The name of the proto_register_* routines an
# proto_reg_handoff_* routines must start in column zero, or must be
# preceded only by "void " starting in column zero, and must not be
# inside #if.
#
# REGISTER_SRC_FILES is assumed to have all the files that need to be scanned.
#
# For some unknown reason, having a big "for" loop in the Makefile
# to scan all the files doesn't work with some "make"s; they seem to
# pass only the first few names in the list to the shell, for some
# reason.
#
# Therefore, we use a script to generate the register.c file.
# The first argument is the directory in which the source files live.
# The second argument is "plugin", to indicate that we should build
# a plugin.c file for a plugin.
# All subsequent arguments are the files to scan.
