# If we're running some kind of ksh, we'll need to source its specific
# configuration if it was defined or if we can find it. Bash and Zsh invoke
# their own rc files first, which I've written to then look for ~/.shrc; ksh
# does it the other way around.
# Unfortunately, this isn't very simple, because KSH_VERSION is set by PDKSH
# and derivatives, and in ksh93t+ and above, but not in earlier versions of
# ksh93.
# If it's not already set, we'll try hard to set it to something before we
# proceed ...
if [ -z "$KSH_VERSION" ] ; then
# Test whether we have content in the .sh.version variable. The odd name
# causes at least Bash to panic, so we suppress errors, and we run it in a
# subshell to work around parsing error precedence.
