ptoanchor is just a wrapper around all sorts of other command-line tools, it runs so many sub-processes, many of them potentially in parallel, that is uses a Makefile and gnu 'make' to do it. This is analogous to the current Hugin stitching system which uses 'make' to manage the stitching process - Actually it is so similar that it wouldn't be difficult to plug this into the Hugin Batch Processor and have end-to-end alignment and stitching.

The hugin code for creating Makefiles mixes the stitching logic with all the complexity of the `make' syntax, so for Panotools::Script I've created a library that separates out the low level Makefile stuff:

I do think this is quite cute, executing thousands of sub-processes is easy to code, and something similar could be done in c++ to make the Hugin stitching process more transparent and extensible.
