detect gzip encoding by file extension, and use gzip library accordingly
add param support for runners
update bootstrap.py
fix running of tests via buildout
add support for initializers
add the punix 'parallel unix' backend, allowing local jobs to use multiple cores. also, added an option to specify the shell to be used for executing jobs instead of the default /bin/sh.
add 'inputfile' option, which allows the user to pass a file containing all the input files to be processed. in case of very large jobs, this works around the limit of what can be passed on the command line
