+.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.
