If you want code that will work on a variety of systems, the only way to do that portably is to write portable code to begin with.

You can't magically take a script that works on AIX systems using options that are only available on AIX and make it work on HP-UX, Solaris, and Linux systems. You can't magically take a script that works on HP-UX systems using options that are only available on HP-UX systems and make it work on AIX, Solaris, and Linux systems. You can't magically take a script that works on Solaris systems using options that are only available on Solaris systems and make it work on AIX, HP-UX, and Linux systems. You can't magically take a script that works on Debian Linux systems using options that are only available on Debian Linux systems and make it work on AIX, HP-UX, Solaris, and Red Hat Linux systems. ...

But, you can write a strictly conforming POSIX shell script and have it work perfectly on AIX, HP-UX, Solaris, and OS X systems (and if you're lucky, there is also a good chance that it will also work on many Linux systems and on many BSD systems).

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
