Description

13       Print values of the specified keywords from the given image header.  By
14       default  they  are all listed on one line, separated by spaces.  The -v
15       flag causes the keyword names and values to be printed, one keyword per
16       line.   To  read  keywords from a list of files, substitute @<listfile>
17       for the file names on the command line.  To read a lot of keywords, put
18       them, one per line, in a file and substitute @<keylistfile> on the com‐
19       mand line.  If two @ commands are present, the program will figure  out
20       which contains file names and which contains keywords.
