Hi all, I've made a new egg r7rs-tools that provides r7csc and r7csi, which are roughly r7rs-only-by-default versions of csc and csi (essentially, the initial environment is only (scheme base) by default, no scheme, (chicken base) or (chicken syntax)). The egg has passed test-new-egg, and the release-info url is here:
https://code.dieggsy.com/r7rs-tools/plain/r7rs-tools.release-info I've not tested this for very large or complicated projects, but it seems to work so far for simple examples. Docs are available here: https://wiki.call-cc.org/eggref/5/r7rs-tools - Diego
