This probably is a stupid question but could you explain how exaxtly a person should use the command line version. Because when I use it, I get a corrupted RCO and I used the help command too. It's probably just me being stupid but could you give an example. This is what I have now:

Files\Include\rcomage.exe compile Files\Build\system_plugin_bg\system_plugin_bg.xml Files\TEMP\VSH\resource\system_plugin_bg.rco --pack-hdr zlib

This is being used in a theme installer I'm making. After the user picks the options and waves and other stuff it builds the RCOs accordingly. How would I do this because right now I'm lost. The XML file and other stuff works fine in the GUI version though.
