If a search for "just meta tags" could be handled by SWISH directly that 
would be much better. I have only been writing extensions to SWISH in Perl 
to add functionality that SWISH doesn't already have. I'm not familiar with 
the C source code, so playing around with it is not my first choice.

I find that for quick results, treating SWISH as a black box and wrapping 
it in Perl is a pretty good solution (it keeps SWISH simple as well). Perl 
is so good at anything involving text that it makes writing such extensions 
a fairly easy task. Thus you can customise SWISH for a particular task in a 
very short space of time.

I don't have the option of compiling SWISH for all platforms, so Perl's 
platform portability means that I can write these extensions for people 
using operating systems other than Windows NT, such as UNIX etc.
