# This tool adds the builder:

# This is useful for doing:
#
# k = env.RecursiveInstall(dir_target, dir_source)
#
# and if any thing in dir_source is updated the install is rerun
#
# It behaves similar to the env.Install builtin. However it expects
# two directories and correctly sets up the dependencies between each
# sub file instead of just between the two directories.
#
# Note in also traverses the in memory node tree for the source
# directory and can detect things that are not built yet. Internally
# we use the env.Glob function for this support.
#
# You can see the effect of this function by doing:
#
# scons --tree=all,prune
#
# and see the one to one correspondence between source and target
# files within each directory.
