Micro string library: documentation

 ustr (Micro string library) is a string API for C. It has tiny overhead over
 just plain strdup(), is much safer, is easier to use, is faster for many
 operations, can be used with read-only or automatically allocated data. You
 don't even need to link to the library to use it (so there are no
 dependencies).

 This package provides HTML documentation and examples.
