-.SH NAME
-pswrap \- creates C procedures from segments of PostScript language code

-.SH DESCRIPTION
-.LP
-.B pswrap
-reads input from
-.I inputfile
-and creates C-callable procedures, known as wraps, that send PostScript
-language code to the PostScript interpreter.
-.I inputfile
-contains segments of PostScript language code wrapped with a C-like
-procedure syntax.
-.LP
-Wraps are the most efficient way for an application to communicate with the
-PostScript interpreter. For complete documentation of
-.B pswrap
-and the language it accepts, see "pswrap Reference Manual"
-in \fIProgramming the Display PostScript System with X.\fR
-.LP
-
-.SH OPTIONS
-.LP
-.TP
-.I inputfile
-A file that contains one or more wrap definitions.
-.B pswrap
-transforms the definitions in
-.I inputfile
-into C procedures. If no input file is specified, the standard
-input (which can be redirected from a file or pipe) is used. The input file
-can include text other than wrap definitions.
-.B pswrap
-converts wrap definitions to C procedures and passes the other text
-through unchanged. Therefore, it is possible to intersperse C-language
-source code with wrap definitions in the input file.
-.RS
-.LP
-.I Note:
-Although C code is allowed in a pswrap input file, it is not allowed
-within a wrap body. In particular, no CPP macros (for example, #define) are
-allowed inside a wrap.
-.RE
-.TP
-.B \-a
-Generates ANSI C procedure prototypes for procedure definitions in
-.I outputCfile
-and, optionally,
-.I outputHfile.
-The
-.B \-a
-option allows compilers that recognize the
-ANSI C standard to do more complete type checking of parameters. The
-.B \-a
-option also causes
-.B pswrap
-to generate const declarations.
-.RS
-.LP
-.I Note:
-ANSI C procedure prototype syntax is not recognized by most non-ANSI C
-compilers, including many compilers based on the Portable C Compiler. Use the
-.B \-a
-option only in conjunction with a compiler that conforms to the ANSI C Standard.
-.RE
-.TP
-.BI \-h " outputHFile"
-Generates a header file that contains extern declarations for non-static
-wraps. This file can be used in #include statements in modules that use
-wraps. If the
-.B \-a
-option is specified, the declarations in the header file
-are ANSI C procedure prototypes. If the
-.B \-h
-option is omitted, a header file is not produced.
-.TP
-.BI \-o " outputCFile"
-Specifies the file to which the generated wraps and passed-through text are
-written. If omitted, the standard output is used. If the
-.B \-a
-option is also specified, the procedure definitions generated by
-.B pswrap
-are in ANSI C procedure prototype syntax.
-.TP
-.B \-p
-Specifies that strings passed by wraps are padded so that each data object
-begins on a long-word (4-byte) boundary. This option allows wraps to run on
-architectures that restrict data alignment to 4-byte boundaries and
-improves performance on some other architectures.
-.TP
-.B \-r
-Generates reentrant code for wraps shared by more than one process (as in
-shared libraries). Reentrant code can be called recursively or by more than
-one thread. The
-.B \-r
-option causes
-.B pswrap
-to generate extra code, so use it only when necessary.
-.TP
-.BI \-s " maxstring"
-Sets the maximum allowable length of a PostScript string object or
-hexadecimal string object in the wrap body input. A syntax error is reported if a
-string is not terminated with ) or > within
-.I maxstring
-characters.
-.I maxstring
-cannot be set lower than 80; the default is 200.
