# Purpose
#
# The purpose of this script is to take a minimal set of data and apply
# it to the ~/G/L/A directory tree to implement a "theme" for AfterStep.
# This script works on the assumption of version 1.5 or greater.
###################
# Scope
#
# Here are the individual components that I think make up a theme.
# Obviously, the individual look file in its entirety. Also the Wharf
# TextureType, Pixmap, TextureColor, and BgColor. The Pager Font,
# SmallFont, Fore, Back, Hilight, DesktopImage, Image, Align,
# BalloonFore, BalloonBack, BalloonFont, BalloonBorderWidth, and
# BalloonBorderColor. Finally, the WinListFont, WinListFore,
# WinListBack, and WinListJustify. As an added bonus, a scheme will
# be included to allow icons for both Wharf and the database to be
# replaced.

# Assumptions
#
# * Unique themes for each desk will not be supported at this time.
# * Modules that support multiple instances must be formed like this:
# <new_prefix>Pager versus Wharf<bad_suffix>. Examples might be
# MyPager, GoodPager, MyWharf not Wharf2, WharfBad, PagerBad
###################
# Strategy
#
# A new themes directory will be placed in the ~/G/L/A/desktop
# directory. Each new theme will have its own subdirectory under
# that. Each theme's subdirectory will duplicate the ~/G/L/A/desktop
# subdirectores plus put its own "patches" to the module configuration
# files there. For example, let's say I had a theme called 'foo'. I
# would then have a directory ~/G/L/A/desktop/themes/foo. Under that
# I would have the 16bpp, 8bpp, common subdirs and possibly 24bpp and
# other bit depths. Also in the ~/G/L/A/desktop/themes/foo directory
# would be wharf.foo, pager.foo, and winlist.foo. OK, that sets up
# how the theme data is stored.
#
# Now on the startmenu, in the Decorations submenu would be a new menu
# called "Themes". When the startmenu is built, it will scan the
# ~/G/L/A/desktop/themes directory to determine what themes are
# "installed". When the user then selects a theme from the startmenu,
# this theme installer script will then be executed to modify the
# appropriate files in the non-configurable directory.
