Sure, parallel is an awesome program. However I already explained why I
chose to write this patch and added more functionality to bacman: Save
time for other users.
The added code is modest in size and enables anyone to significantly
speed up their bacman process by having a look at the man page and
without downloading an additional ~5000 line perl program.
Please also consider that this patch is about more than just
parallelization: It adds a manual page, some useful command line
options and let bacman handle abort signals.
