# FNA is a reimplementation of the Microsoft XNA Game Studio 4.0	#
# Refresh libraries.							#
# Thanks to the great work by Ethan Lee (flibitijibibo) games using FNA	#
# are highly portable and can even run on OpenBSD. Please refer to	#
# https://fna-xna.github.io/ for more information about FNA.		#

#########################################################################

# TODO:
# - fix TODOs
# - fails to detect XNA in Streets of Fury EX because of whitespace; resolved after renaming .exe
# - update the creator for dllmap file; based on fnaify.dllmap.config
# - mention package fnaify-extralibs in documentation
# - add option to add runtime exe_flags to run mode
# - AVNT: find a way to have Steam deactivated for this one in libSteamworksNative.so
# - add flag to create log file (for fnaify, as well as the output from the game)
# - document '--' to end getopts parsing; can make it clear when to pass remaining args to game
# - add check for ffmpeg if needed

USAGE="
Usage:

$(basename "$0") [-i|-y] [-hsv] [-c configfile] [-D depdir] [-d gamedir] [-f frameworkfile | -F frameworkversion] [-m monopath] [userflags]

-c: specify config file for dllmap
-D: add directory to native library loader
-d: game directory
-F: framework version
-f: framework file
-h: print usage information
-i: interactive mode
-m: add directories to MONO_PATH
-n: skip the library check
-s: force (re-)running setup
-y: non-interactive mode; automatically replies 'yes' to all recommended choices
-V: display version
-v: verbose output

<userflags> are optional. These arguments are passed to the game runtime.
