# c2z - environment conversion tool
# Contributed by Bart Schaefer
# (Tweaked a bit by Paul Falstad)
# (Tweaked again by Bart Schaefer)
#
# This is a quick script to convert csh aliases to zsh aliases/functions.
# It also converts the csh environment and local variables to zsh.  c2z
# uses the csh to parse its own dot-files, then processes csh output to
# convert the csh settings to zsh.
#
# When run as a zsh function, c2z runs csh as if it were an interactive
# shell whenever the parent zsh is interactive.  When run as a shell
# script, the -i switch can be used to force this behavior.
#
# The -l (login) switch causes csh to run as if it were a login shell.
# This is done "properly" if c2z is used as a zsh function, otherwise
# it's faked by explicitly sourcing .login.  Use with caution if your
# .login initializes an X server or does other one-time-only startup
# procedures.
#
# usage:
#	c2z [-i | -l | filename]
#
# You can use this script in your .zshrc or .zlogin files to load your
# regular csh environment into zsh; for example, in .zlogin:
#
#	. =(c2z -l)
#
# This is not perfect, but it gets most common aliases and variables.
# It's also rather time-consuming to do this every time you log in.
# However, if you're moving from csh to zsh for the first time, this
# can get you started with a familiar environment right away.
#
# In case your mailer eats tabs, $T is set to expand to a tab.
#
T="`echo x | tr x '\011'`"

# If we're zsh, we can run "- csh" to get the complete environment.
