NAME

       nydiff - tool to compare two versions of a specialized-format patch

SYNOPSIS

       nydiff oldpam newpam name options [ print ] [ .go ]

DESCRIPTION

       nydiff  is  a  tool in the Nypatchy suite of programs for working with Patchy Master Files
       (PAM files); see nypatchy(1).  Specifically, it compares two  different  versions  of  the
       same  PAM  file  and generates a "correction patch" that can be used by nypatchy to update
       the older version to the newer version.

USAGE

       The parameter oldpam is the name of the older version of the PAM file (a default extension
       of  ".car"  is assumed), newpam is the name of the newer version, print is the output file
       to write to (the default is standard output if omitted), and  options  is  a  sequence  of
       single-character flags.  The parameter name is the name to be used for the correction file
       to be generated (the specific filename will be name.ucra for a correction patch to be used
       by Nypatchy).

       The  command should be ended with ".go" unless one wants to enter the Nypatchy interactive
       shell.

OPTIONS

       Note that options should be  given  as  a  single  string  of  characters  with  no  space
       separation  and  no  use  of  the  - character (except that it can be used in place of the
       options field if no options are desired).  Alphabetic options are not case-sensitive.

       A      "anyway" - Bypass the first sanity check on sufficient matching.

       F      "force" - Bypass the second sanity check on sufficient matching.

       H      Print help information only.
