Description: Script to install an Xash3D engine full game client or dedicated server with game data from steamcmd
Server tested on Debian 11 ; Client tested on Ubuntu 20.04
Origin: https://git.la10cy.net/DeltaLima/xash3d-installscript

You can override following variables default values:
XASH_INSTALL_DIR, XASH_DS_PORT and XASH_BUILD_DIR

Example:

1) Install server version '0.19' into '~/opt/xashds_oldengine'

  XASH_INSTALL_DIR=~/opt/xashds_old $0 server install 0.19

2) Update client version 0.20 located in ~/Games/Xash3D where the build directory is as well
  
  XASH_INSTALL_DIR=~/Games/Xash3D XASH_BUILD_DIR=\$XASH_INSTALL_DIR/build $0 client update 0.20

Resources we are using:
$steamcmd_url
$hlds_url
0.20: https://github.com/FWGS/xash3d-fwgs
0.19: https://gitlab.com/tyabus/xash3d"
