# This script is a small wrapper to the PCSX2 exectuable. The purpose is to
# 1/ launch PCSX2 from the same repository every times.
# Rationale: There is no guarantee on the directory when PCSX2 is launched from a shortcut.
#            This behavior trigger the first time wizards everytime...
# 2/ Change LD_LIBRARY_PATH to uses 3rdparty library
# Rationale: It is nearly impossible to have the same library version on all systems. So the
#            easiest solution it to ship library used during the build.
# 3/ Set __GL_THREADED_OPTIMIZATIONS variable for Nvidia Drivers (major speed boost)
