Detailed Description

A convenience output stream that will accumulate what is streamed to it and then, on destruction, format the accumulated string using the fmt program (via the argagg::fmt_string() function) to the provided std::ostream.

Example use:

* {
*   argagg::fmt_ostream f(std::cerr);
*   f << "Usage: " << really_long_string << std::endl;
* } // on destruction here the formatted string will be streamed to std::cerr
* 

Note

This only has formatting behavior if the __unix__ preprocessor definition is defined since formatting relies on the POSIX API for forking, executing a process, and reading/writing to/from file descriptors. If that preprocessor definition is not defined then this class has the same overall behavior except the output string is not formatted (basically streams whatever the accumulated string is). See arggg::fmt_string().
