# This script does a full build of unison, installs it to a DESTDIR,
# and then cleans the build. While doing so, it asks the operating
# system to log call system calls. That log is examined for pathname
# lookups, such as are invoked by exec system calls, and the names
# extracted. The list is filtered to absolute paths with /bin or
# /sbin, with /usr and /usr/pkg projected down, and then uniquified
# and counted. The point is to make a list of programs in bin-type
# directories that may have been executed.
