--[[ mod format: lua script that defines:
name - a name that is displayed in list
author - mod author, also displayed
description - mod description
OPTIONAL:
raws_list - a list (table) of file names that need to be copied over to df raws
patch_entity - a chunk of text to patch entity TODO: add settings to which entities to add
patch_init - a chunk of lua to add to lua init
patch_dofile - a list (table) of files to add to lua init as "dofile"
patch_files - a table of files to patch:
filename - a filename (in raws folder) to patch
patch - what to add
after - a string after which to insert
MORE OPTIONAL:
guard - a token that is used in raw files to find editions and remove them on uninstall
guard_init - a token for lua file
[pre|post]_(un)install - callback functions. Can trigger more complicated behavior
