#	PowerShell Script:	Script to compile VHDL libraries for GHDL
# 
#	Authors:						Patrick Lehmann	(ported batch file to PowerShell)
#											Brian Davis			(contributions to the batch file)
#											Tristan Gingold	(initial batch file for compilations on Windows)
# 
# Description:
# ------------------------------------
#	This is a PowerShell script (executable) which:
#		- sets up a compilation environment
#		- test all dependencies
#		- pre processes VHDL files with GHDLFilter
#		- analyses VHDL files with GHDL
