The idea of Sire has expanded over time to be a simple, clear and functionally complete build utility that covers all (or as many as practical) areas of building applications. Since it is quite general in its design it can be put to use for many other tasks. But principally Sire is a build utility.
If you like Sire great. If you think you can improve Sire then please let me know.
N.B. Sire is under going a name change from 'Jake' to 'Sire' to avoid confusion with the Jake Project. The current development version will become the first version of Sire (formally Jake). The name change will involve some functional changes. However, Sire will be backwards compatable with Jake.
