The Regular Old Text Formatting Language (ROTFL), created by Chris Lumens <chaos@bangmoney.org>, is a simple textual formatting language comparable to the HyperText Markup Language (HTML). It is so comparable that I wrote a Perl script to convert from ROTFL to HTMl.
The current version is 0.02.0 and may be downloaded as the file rotfl2web. Just make it executable (chmod a+x rotfl2web) and run it. At least the input ROTFL file must be given. An optional argument is the output HTML file.
For even more information about ROTFL, see my ROTFL subsubsite.
Sweet conditional block in the code. Wish I had put a license on it.
