When trying to run ‘make distcheck’ on gnome-user-docs, I got this error:

make[1]: execvp: /bin/sh: Argument list too long

This roughly translates to “You have so much documentation translated into so many languages that your poor build system can’t handle it.” Congratulations to everybody involved in reaching this wonderful error.

Update: I’ve added a custom distdir target to yelp.m4 to fix this problem. If you maintain a package with a large document and a lot of translations (gnome-user-docs, ubuntu-docs), install yelp-tools 3.3.2 before making your next release. You may need to run ‘make distclean’ and rebuild completely to get the new build rules.
