42## DIST_SUBDIRS is typically automatically derived by automake including
43## all possible SUBDIRS values, as even items which are not built are
44## typically distributed.
45##
46## To allow us to avoid configuring the libevent tearoff entirely when
47## it is not needed, we define DIST_SUBDIRS manually excluding libevent
48## when not building it, and in that case arrange for its distribution
49## with EXTRA_DIST copying the entire directory and libevent-dist-hook
50## cleaning unwanted VCS remnants.
51##
52## When we are building libevent, it is distributed conventionally, by
53## recursive make dist in sntp including libevent.
