-#
-# A minimal alternative to djb redo that doesn't support incremental builds.
-# For the full version, visit http://github.com/apenwarr/redo

-# The author disclaims copyright to this source file and hereby places it in
-# the public domain. (2010 12 14; updated 2019 02 24)

-USAGE="
-usage: do [-d] [-x] [-v] [-c] <targets...>
-  -d  print extra debug messages (mostly about dependency checks)
-  -v  run .do files with 'set -v'
-  -x  run .do files with 'set -x'
-  -c  clean up all old targets before starting
-
-  Note: do is an implementation of redo that does *not* check dependencies.
-  It will never rebuild a target it has already built, unless you use -c.
