# Call cscope (a program by Sun - sort of an intelligent front end to
# grep) with the right sort of settings for tkeden.

# This is of course, only of some use on a Sun platform which has the cscope
# tool installed :)

# Name of temporary file to use - uses the PID of this shell to make the
# name unique.

# Create the temporary file. Actually a little bit of shell so we can call
# emacsclient with the correct arguments (can't set EDITOR to
# 'emacsclient someargs' unfortunately). Note need to escape the $*
# (which means all arguments passed to this shell). The sleep is so that
# we have time to see any error messages.

# Make the temporary file executable.
chmod +x $TEMPFILE

# Make cscope invoke the file as an editor.

# Run cscope. Make it display which directory the code is in (-p2). It is
# interested in C (.c and .h), lex (.l), and yacc (.y) source files, but
# to get it to look at Eden and Tcl files in lib, I have to specify exactly
# which files to look at rather than using the -s option for each directory.

# Finally, remove the temporary file.
