Example of a simple project, which builds an executable using g++.
All the transformations are specified explicitly.
It illustrates the use of project identifiers to refer to other targets
and also project requirements.
Interesting commands would be
bjam
bjam release
bjam release clean
bjam release debug-symbols=on
Also, you can use jam's "-n" option to check if "debug"/"release" have any
effect on commands executed. (Note that "-n" should go before any non-option
elements on command line).
Example of using custom command to create one file from
another, using the builtin 'make' rule.
