I don't understand this sentence either, because the file http://git.savannah.gnu.org/cgit/emacs/elpa.git/tree/elpa-admin.el?h=3Delpa= -admin seems to create the packages, so every package in the elpa built from=20 the git should be the same. One could check whether all packages on ELPA=20 are also in the git and vice versa. Also, some packages might not be=20 `external` in the language of ELPA, so not residing in an `external/*`=20 branch. Best, Johannes -------------------- End of forwarded message --------------------
