Yes it can. Actually another part of the (many) reason(s) I rewrote the thing from scratch is that I needed two sets of gnulib files in the master branch of GNU M4 - one set for libm4.la for the module api runtime, and things like gnu-getopt and version-etc (IIRC) in the main M4 binary. I think this setup is a fairly common requirement for any project that installs libraries and a binary or two, so I was rather surprised at how difficult it was to tease that functionality out of the gnulib bootstrap. I haven't yet updated the M4 bootstrap script to use my rewrite (it still uses the bespoke script the Eric and I wrote), so I can't point you at a direct example, but the extension mechanism is very straight forward and easy to understand from the copious comments; and I have posted bootstrap.conf updates to adopt my rewrite into several projects here on the list and to my github account to show how straight forward extending it is: a simple matter of writing a hook function or two. If you decide to go ahead and try my bootstrap script, and get stuck anywhere, I'd be happy to help write the bootstrap.conf parts for you since I can also use them to move M4 master to my saner script. If you decide to go ahead and try my bootstrap script, and finish the multi-gnulib instance hook function without any help, please ping me afterwards if you don't mind me adopting it for M4 too :) Cheers, -- Gary V.
