       Minimum unique abbreviation of option is acceptable.  You may use  dou-
       ble  hyphens  instead  of single hyphen to denote options.  You may use
       white space in place of the equals sign to separate an option name from
       its value.


       This program is part of Netpbm(1).

       pnmcomp  was  obsoleted  by pamcomp(1),introducedwithNetpbm10.21 (March
       2004).  pamcomp is backward compatible with  pnmcomp,  plus  adds  many
       additional  functions, including the ability to process PAM images, and
       tends to produce better transparency results.

       pnmcomp remains in the Netpbm package because  it  probably  has  fewer
       bugs for now than pamcomp, and is faster.  Some day, pnmcomp will prob-
       ably become an alias for pamcomp.

       You can use the pamcomp documentation for pnmcomp, considering the fol-
       lowing differences:

       ·      pnmcomp options are a subset of pamscale’s, as
                   documented above.

       ·      pnmcomp always assumes the input is linear, as pamcomp
                   does when you specify its -linear option.

       ·      pnmcomp cannot process PAM images.
