"Call me Ishmael." Moby Dick "It was the best of times, it was the worst of times." A Tale of Two Cities "ed is the standard text editor." UNIX Programmer's Manual, 1971cLIeNUX ed has some extra user-feedback over GNU ed. Error messages are more verbose, a bit more error-specific, and there is an L command to print a short command reminder message. cLIeNUX ed is also defaulted differently. cLIeNUX ed starts with an ed>> prompt, and the -H text error report switch is on by default.
cLIeNUX ed, being a derived work of GNU ed, is released under the terms of the GNU GPL.
