# This csh alias named C shows how to include an if-else test in an alias.
# The alias definition is inside double quotes with two backslashes at
# the end of each line.  An outer eval command, which is surrounded by
# single quotes, does the work when the alias is invoked.  It's ugly,
# but it works (on the C shells where we've tried it, at least...).

# COMPILE AND chmod C PROGRAMS; DON'T USE .c ON END OF FILENAME.
