Remark

Remark is a markup language similar to BBCode. It is not entirely compatible with BBCode, but the differences are not that significant.

It was designed with the following goals in mind.

Liberal input:
Any input should be able to be accepted and handled in a reasonable an predicable manner.

Strict output:
All output can be valid XHTML (including properly nested output). Output must be consistent and semantically correct (no line breaks when we really want new paragraphs)

Small learning curve:
It is as compatible with BBCode as possible, except where it would violate the above requirements. Certain aspects of BBCode are simply broken, they are intentionally dropped.

Extensible:
It is possible to create new tags or modify current ones with relatively little effort.
