duktape/Makefile

#
#  Makefile for the Duktape development repo.
#
#  This Makefile is intended for ONLY internal Duktape development
#  on Linux (or other UNIX-like operating systems), and covers:
#
#    - Building the Duktape source distributable.
#    - Running some basic test cases.
#    - Building the duktape.org website.
#
#  The Makefile now also works in a very limited fashion with Cygwin,
#  you can 'make dist' as long as you have enough software installed.
#
#  The source distributable has more platform neutral example Makefiles
#  for end user projects (though an end user should really just use their
#  own Makefile).
#
#  YOU SHOULD NOT COMPILE DUKTAPE WITH THIS MAKEFILE IN YOUR PROJECT!
#
#  When creating actual distributables, always use a clean checkout.
#
#  External projects are downloaded on-the-fly.  Clone git repos shallowly
#  (--depth 1) whenever possible.  With build-critical resources, use a
#  specific version instead of "trunk".
#
#  The makefile should work with -jN except for the 'clean' target, use:
#
#    $ make clean; make -j4
#

# A few commands which may need to be edited.  NodeJS is sometimes found
# as 'nodejs', sometimes as 'node'; sometimes 'node' is unrelated to NodeJS
# so check 'nodejs' first.
