+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."
