Obviously not, in 1990 it would have been published to Usenet group comp.sources, and all you would get would be source. OK, perhaps also a Makefile and a man page. (All packed in a .shar text file, a "shell archive" script that would run and unpack itself.)

Also, at least BSD used to come with /bin/mail, which would send mail from the command line as described. 'mail -s test [email protected] < file.txt', if memory serves.
