The proc named _exec_impl is used to actually invoke the compiler.
This chunk invokes it:
set cmd "exec $prog $prog_flags $prog_args > exec.out 2> exec.err"
if {[info exists ::env(JACKS_EXEC_DEBUG)]} {
puts stderr "JACKS_EXEC_DEBUG: $cmd"
}
eval $cmd
This is wrapped in a 'catch' clause; Tcl's exec command throws an
exception if the exec "fails", which in Tcl means that either it
really fails (command not found or something) or that the command
returns a non-zero exit status. I'm not sure how this works on other
platforms.
Toni> and why is a cvs client needed to generate the change file (with

Yeah, I've always wondered about this myself. The jacks logging stuff
seems a bit user-unfriendly. I'm sure it can be deactivated somehow.
