Part of the release process: record the API. To do this, try something like: cd ~/build/tmp/.tmp-1.6 ~/build/.gnu/guile-scripts/scan-api \ "/home/ttn/build/.gnu/guile-core-1.6/pre-inst-guile ." \ libguile/.libs/libguile.so.10.0.0 \ > ~/build/.gnu/guile-core-1.6/doc/guile-api.alist Note that the guile-api.alist location is fixed (other tools depend on it).
