+Loads plugins' Info.lua and dumps its g_PluginInfo into various text formats
+This is used for generating plugin documentation for the forum and for GitHub's INFO.md files
+
+This script can be used in two ways:
+Executing "lua InfoDump.lua" will go through all subfolders and dump each Info.lua file it can find
+ Note that this mode of operation requires LuaRocks with LFS installed; instructions are printed
+ when the prerequisites are not met.
+Executing "lua InfoDump.lua PluginName" will load the Info.lua file from PluginName's folder and dump
+only that one plugin's documentation. This mode of operation doesn't require LuaRocks
