Yes, this is a great idea and is on my todo list. Although the tutorial is
sprinkled with examples, it is not easy to find what you need without
reading through the entire documentation.

I have some thoughts about this as well. It is possible to write a script
that filters this giant error output and returns a much more compact and
human readable error description. For example, replace the page-long
description of an 8-bit rgb view with 'rgb8_view_t', etc.
It is also possible to find the common causes for the errors and print them
as hints. For example, if you pass the wrong view you typically get an error
at a given GIL line. One could track common errors and manually add hints
for them. A more advanced system could leverage the debugging power of other
developers. For example, once you figure out and fix the error, you submit
the error message along with an English description of what was wrong to a
server. The next time you get an error, your script can check online for the
error trace and give you a list of English descriptions of common causes...
This script would need to be tuned for each compiler and platform, however.
But it seems like a tool that many other boost libraries could benefit from.
Just a thought... Any volunteers?
