# Warning: Tk definitions are very similar to Tcl definitions but
# are not precisely the same.  There are a couple of differences,
# so don't do changes to Tcl thinking you can cut and paste it do 
# the Tk differences and later simply substitute "Tk" for "Tcl".
# Known differences:
#  - Acceptable Tcl major version #s is 8.2-9.* while Tk is 8.2-9.*
#  - Searching for Tcl includes looking for tclInt.h, Tk looks for tk.h
#  - Computing major/minor versions is different because Tk depends on
#    headers to Tcl, Tk, and X.
#  - Symbols in tkConfig.sh are different than tclConfig.sh
#  - Acceptable for Tk to be missing but not Tcl.

# Ok, lets find the tk source trees so we can use the headers
# If the directory (presumably symlink) named "tk" exists, use that one
# in preference to any others.  Same logic is used when choosing library
# and again with Tcl. The search order is the best place to look first, then in
# decreasing significance. The loop breaks if the trigger file is found.
# Note the gross little conversion here of srcdir by cd'ing to the found
# directory. This converts the path from a relative to an absolute, so
# recursive cache variables for the path will work right. We check all
# the possible paths in one loop rather than many seperate loops to speed
