arcfile is the name of an arc file to convert to tarred, compressed form. 
The file must have a .arc extension, but only the base name needs to be
given.  If no output file name is given, it will be created in the current
directory with the name being the arcfile basename followed by .tar.EXT.
If the -c option is given, compress will be used, and EXT will be Z.
The default (also available with -g) is to use gzip, in which case EXT
is gz.  If the basename is too long the extension may be truncated.  All
uppercase letters in the names of files in the archive are moved to lowercase."
