Source code highlighting filter

This little program is a wrapper around Lorenzo Bettini's GNU source-highlight program, which can be used as an Apache filter to highlight source code in Web pages on the fly. Here's an example: in your Web page source you might have


<highlight lang="python">
  ## This is a Python snippet
  import os, re

  print "Foo and bar"
  sys.exit(0)
</highlight>

This code highlighting filter will (depending on configuration details) turn this into something like


## This is a Python snippet
import os, re

print "Foo and bar"
sys.exit(0)

You can also use the highlighting tag to refer to a code file with a system or network path, for example:


<highlight lang="python" href="foo.py" />
<highlight lang="xml" href="/www/path/to/bar.xml" />
<highlight lang="fortran" href="http://www.example.com/baz.f" />

Nice features of this highlighting filter include:

automatic support for all source-highlight input languages
customisable higlighting tag and namespace prefix
configuration via environment variables and command line switches
optional caching of results using MD5 hashes
inline referencing of local and remote code files
input on stdin or from file specified by command line --input switch

Requirements

Python
GNU source-highlight
BeautifulSoup Python package
mktemp (standard command line tool - used if caching is disabled)
