# Test RCS's functions.
# The RCS commands are searched for in the PATH as usual;
# to test the working directory's commands, prepend . to your PATH.

# Test RCS by creating files RCS/a.* and RCS/a.c.
# If all goes well, output nothing, and remove the temporary files.
# Otherwise, send a message to standard output.
# Exit status is 0 if OK, 1 if an RCS bug is found, and 2 if scaffolding fails.
# With the -v option, output more debugging info.

# If diff outputs `No differences encountered' when comparing identical files,
# then rcstest may also output these noise lines; ignore them.

# The current directory and ./RCS must be readable, writable, and searchable.
