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.
