#  Bash Script:
#    Script to compile the simulation libraries from Altera
#    Quartus for GHDL on Linux
# 
# Description:
# ------------------------------------
#  This is a Bash script (executable) which:
#    - creates a subdirectory in the current working directory
#    - compiles all Altera Quartus-II simulation libraries and packages
