#  Create a distributable Duktape package into 'dist' directory.  The contents
#  of this directory can then be packaged into a source distributable.
#
#  The distributed source files contain all profiles and variants in one.
#  A developer should be able to use the distributes source as follows:
#
#    1. Add the Duktape source files to their project, whichever build
#       tool they use (make, scons, etc)
#
#    2. Add the Duktape header files to their include path.
#
#    3. Optionally define a DUK_PROFILE (default profile is used otherwise).
#
#    4. Compile their program (which uses Duktape API).
#
#  In addition to sources, documentation, example programs, an example
#  Makefile, and test cases are packaged into the dist package.
