# Re-make the library deliverables in hterm/dist.
#
# The deliverables (things published for use by third parties) are...
#
#  dist/js/hterm_deps.js - Code that hterm depends on from outside of the
#    hterm/ directory.  If you also depend on some or all of these files you
#    may want to make this file yourself.
#
#  dist/js/hterm.js - The hterm code and resources.
#
#  dist/js/hterm_resource.js - Only the resources, used by hterm_test.html.
#
#  dist/js/hterm_all.js - hterm_deps.js + hterm.js.  Most apps can just use
#    this.
