I went through all packages listed in users.txt, extracted the requested modules from the bootstrap.conf / gnulib-cache.m4 / ..., and stored the result in maint-tools/used-modules/. From these lists, one can make statistics.
Note: The list of packages in users.txt is certainly incomplete; according to https://codesearch.debian.net/search?q=gnulib-tool&literal=1&perpkg=1 there are about 150 packages that use gnulib-tool, not only 101. Note: These statistics consider only the *explicitly* requested modules, not those that occur as dependencies. Note: I do *not* mean to imply that a less-used module is somehow less worth than a heavily used module. Number of modules explicitly requested: 1164 Statistics (# of packages, module): 51 getopt-gnu 43 xalloc 43 progname 41 gitlog-to-changelog 39 stdbool 39 regex 38 gettext-h 37 git-version-gen 37 error
