# Build and Test tidy on the latest versions of all of the major platforms. 
#
#   - Build on multiple operating systems, and where possible, multiple
#     architectures. On Windows, we will also build and test MingGW in
#     addition to MSVC.
#
#   - Report the version number for each binary that is built.
#
#   - Run each binary against the regression test suite.
