Edition : 1

Description

Runs cat on tag files <file1> <file2> ...

Output is a tag file.

If the tags are different in each file, the sum of the tags becomes

a new tag.  In this case, the fields for tags that don't exist in a

file are padded with the underscore ("_").  You can change the

padding character with the -d option.

If <file> is not specified or specified as "-" then the command

reads from standard input.
