* First thing always is including Eina:
* @skipline #include
* @until #include
*
* Next we initialize eina and create a string buffer to play with:
* @until strbuf_new
*
* Here you can see two different ways of creating a buffer with the same
* contents. We could create them in simpler ways, but this gives us an
* opportunity to demonstrate several functions in action:
* @until strbuf_reset
* @until strbuf_reset
*
* Next we use the printf family of functions to create a formated string,
* add, remove and replace some content:
* @until strbuf_string_get
* @until strbuf_string_get
* @until strbuf_string_get
*
* Once done we free our string buffer, shut down Eina and end the application:
* @until }

* @example eina_strbuf_01.c
