# On a mac with snow leopard, for nicer terminal colours:

# - Install SIMBL: http://www.culater.net/software/SIMBL/SIMBL.php
# - Download'Terminal-Colours': http://bwaht.net/code/TerminalColours.bundle.zip
# - Place that bundle in ~/Library/Application\ Support/SIMBL/Plugins (create that folder if it doesn't exist)
# - Open Terminal preferences. Go to Settings -> Text -> More
# - Change default colours to your liking.
#
# Here are the colours from Textmate's Monokai theme:
#
# Black: 0, 0, 0
# Red: 229, 34, 34
# Green: 166, 227, 45
# Yellow: 252, 149, 30
# Blue: 196, 141, 255
# Magenta: 250, 37, 115
# Cyan: 103, 217, 240
# White: 242, 242, 242
