otl is a text processor for generating markup from readable lightweight markup. Much of both the input and output formats can be customized. HTML output is bundled as an example. otl supports complex structures such as nested ordered and unordered lists, headers and footers, and tables.
ssqlfs uses a defined file/directory structure to generate an SQL database which corresponds to that file/directory structure. Along with support for one-to-many tables, ssqlfs includes support for representing many-to-many tables. Ideally, the filesystem would be interconvertible with an SQL database, but at this point the functions for generating a file/directory structure from the SQL database remain to be thoroughly tested.
