.SH Description
Delete keyword entries from the header of FITS or IRAF image[s].  If
a keyword does not already exist, ignore it.  To delete keywords in
a list of files, substitute @<listfile> for the file names on the command
line.  To delete a lot of keywords, put them, one per line, in a file
and substitute @<keylistfile> on the command line.  If two @ commands
are present, the program will figure out which contains file names
and which contains keywords.
