NAME
       jpegcom - Read or write the comments of JPEG images

SYNOPSIS
       jpegcom file.jpg ... > list

       $EDITOR list

       jpegcom < list

DESCRIPTION
       This manual page documents briefly the jpegcom command.

       jpegcom  reads or writes comments embedded in JPEG images.  The program
       has two modes of operation.

       When invoked with arguments, jpegcom outputs a list of file  names  and
       comments  to  standard output.  Each file name specified on the command
       line is listed twice in quoted strings, after the  keyword  copy.   The
       two  file  names are followed by comment strings for the image, if any.
       There may be multiple comments per image.

       When invoked without arguments, jpegcom reads a list of file names  and
       comments from standard input.  Lines starting with # are ignored, as is
       white space outside strings.  The file name entries must begin with one
       of  the  keywords copy and rename followed by two file names in quotes.
       Output is written to the second file, and if the keyword is rename, the
       first  file  (input) is removed.  The file names may be followed by any
       number of comment strings, which will be written to the output file.

       Strings are delimited by double quotes "".   The  quote  and  backslash
       characters  must  be prefixed with a backslash (\).  Special characters
       can be embedded by writing their octal code after  a  backslash,  e.g.,
       "\200".   When generating the list, jpegcom obeys the current locale to
       determine which characters should be quoted.
