acl2, acl2-minimal: build standard library, init Before this commit, we only built the main ACL2 executable. Most users will also want the standard library (the "Community Books"), so after this commit, we build the entire `make everything` suite, which includes essentially everything provided in the ACL2 repository. There's also a new top-level package called `acl2-minimal` which has just the core ACL2 executable, for those who really only want that. Future work: modularize the build so that we can support multiple different subsets of the standard library. A lot of the stuff in this complete build is probably superfluous to almost all users. Also, because some of the books have unclear or idiosyncratic licenses, the full build will not be cached on cache.nixos.org, and installing it will mean spending a few hours building it. So it would be good to have a pared down build which excluded non-free books and things that people rarely or never use. 2020-02-24 05:12:37 +00:00			`From b0ccf68f277d0bd5e6fc9d41742f31ddda99a955 Mon Sep 17 00:00:00 2001`
