What is the purpose of selecting a configuration?
Is it to go quicker in the implementation you are interested in?
In that case, I think we need a catch-all option, because I like
being prompted by vim that several implementations exist and I can
choose one of them.

I think build-tags.sh would be a better name.

On the implementation, I have few comments:
	- is there a way to re-use the skip list when including the related files?
	- you can remove tile from this patch
And for the details:
	- why a bash shebang where /bin/sh would be wider?
	- verbose option should be -v (with getopts)
	- please use $() instead of backquotes
	- please avoid one-line functions used only once like doctags

I can help you with this script if needed.
