#=6/2006=====================================Version 0=#
#=========== "human readable" grid calendar ==========#
#
# To test :
#
# .\gadget-calendar
# °shows month calendar with current day
# highlighted (red on white by default)
# .\gadget-calendar "6/2006"|tee -file calendar.txt
# .\gadget-calendar "june 2006"|tee -file calendar.txt
# .\gadget-calendar "juin 2006"|tee -file calendar.txt
# °outputs june 2006 month grid and writes it
# to calendar.txt file
# .\gadget-calendar -fullyear 2006|tee -file calendar.txt
# °outputs full year 2006 grid (3 x 4) and writes it
# to calendar.txt file
#
# NOTE : gadget-calendar without parameters doesn't
# highlight current day if you call it directly
# after you've launched PowerShell (probably a
# console bug).
# If you recall gagdet-calendar, that works.
