then something is severely broken!
here is a text of alpha-linux/texshow as fetched directly from perforce
repository by p4web:
===========================================
#!/bin/sh
test -f /bin/sh5 && test -z "$RUNNING_SH5" \
&& { UNAMES=`uname -s`; test "x$UNAMES" = xULTRIX; } 2>/dev/null \
&& { RUNNING_SH5=true; export RUNNING_SH5; exec /bin/sh5 $0 ${1+"$@"}; }
unset RUNNING_SH5
test -f /bin/bsh && test -z "$RUNNING_BSH" \

# hack around a bug in zsh:

Also, texutil is different for these two directories.
WHAT'S GOING ON?

i.e. it is the same as rm -rf all the repository and then sync? :)
no - i don't want this :) i want to verify the files without
re-downloading them in full (like CVS does).

checking scripts will become a non-issue when you will not duplicate
them in several locations.
you'll just build texlive for any platform, and move the scripts to a
generic scripts dir, and all binaries submitted to you will not
include any platform-independent scripts.
otherwise, there will always be a mess in different script files.
