NAME

       nypatchy - tool to work with specialized-format patches

SYNOPSIS

       nypatchy pam fort cradle print cc as data [ fort2 cc2 as2 data2 ]

DESCRIPTION

       nypatchy  is  a	tool for working with Patchy Master Files (PAM files).	A PAM file is an ordinary text file (generally with a three-letter
       extension of ".car") that holds source code interleaved with special pre-processing instructions for nypatchy.  The source code may  be	in
       C,  FORTRAN, assembly language, or a combination of these.  The pre-processing instructions allow one to maintain separate optional patches
       independently, for instance in the case of architecture-specific code.  Details of the pre-processing commands used by nypatchy are  beyond
       the scope of this man page; the reader should refer to the full manual available from CERN.

       Telling	nypatchy which set of patches to use may be done on standard input or via a so-called cradle file.  Typically the cradle file will
       contain one or more +USE statements as well as +EXE and +QUIT, for instance in the case of the isajet Monte Carlo generator:

       +USE,*ISAJET
       +EXE
       +PAM
       +QUIT

USAGE

       In the command line shown above, pam is the PAM file, if any.  fort is the name of the primary output source code file, if any.	cradle	is
       the name of the cradle file, if any (default is standard input, for instance a here-doc).  print is the name of the file to receive printed
       output (the default is standard output).  cc, as, data are the names of the source code output files for data  types  CC,  AS,  DATA.   The
       remaining parameters are the source code output files to receive diverted material for respective data types FORT, CC, AS, DATA.

       Parameters  may be omitted by substituting a dash - for them.  Trailing parameters may be cut short by giving "." or ".go"; the latter com-
       mences execution immediately rather than starting the nypatchy interactive prompt.

       nypatchy will return to the shell a code of 0 if successful, 1 if there is a warning, and 2 if an error occurs.	Since  the  program  stops
       creating  output, but continues to run (in order to check for further errors) if an error occurs, the user should be sure to test the error
       code $? after any nypatchy run.

EXAMPLES

       nypatchy -- xyz .go
	      reads the cradle (instructions) from file xyz.cra, which must list all other files to be used.

       nypatchy .go << EOF
	      <cradle>

       EOF
	      has the cradle given as a here-document.

       nypatchy zebra.car zebra.fca zebra.cra zebra.lis .go
	      reads the PAM file zebra.car, outputting the resulting source code to zebra.fca, taking the cradle  from	zebra.cra,  with  printing
	      done to zebra.lis.

       Running the command "nypatchy help .no" also gives some brief help on usage.
