NAME
       showrgb - display an rgb color-name database


SYNOPSIS
       showrgb [ database ]


DESCRIPTION
       The showrgb program reads an rgb color-name database from a text file and converts it back
       to source form, printing the result to standard output.  The default database is  the  one
       that  X  was  built with, and may be overridden on the command line.  Specify the database
       name without the .txt, .pag or .dir suffix.


FILES
