"
Usage: cons [-h] [ -- [release|debug] [update_server=<host>] [noldd] [demo|light|update] [setup] [gcc=<gcc>] [g++=<g++>] ]

options:
[release|debug]
 Default build type is Debug, specifying '-- release' on the
 command line builds a Release version.
 
[update_server=<host>]
 Compile with a custom AUTOUPDATE_SERVER_NAME as given in <host>

[noldd]
Don't abort if ldd checks fail

[pk3]
Build the pk3s from Conscript-pk3 (default off)

[demo]
 This switch uses -DPRE_RELEASE_DEMO and builds for MPTest
 
[light]
 This switch builds the lightweight dedicated server
 (only wolfded and qagame targets, -DDO_LIGHT_DEDICATED)

[update]
 This builds an update server, serves update installers 

[setup]
 'cons -- setup' will build then execute the setup building scripts
   NOTE: 'cons -- setup' will default to release configuration
 you can use 'cons -- setup debug' to force debug setups building
 reminder: distributed binaries must be configured in release 
   and stripped from symbols
