# This is the main Gruntfile that manages building Edgehill distributions.
# The reason it's inisde of the build/ folder is so everything can be
# compiled against Node's v8 headers instead of Atom's v8 headers. All
# packages in the root-level node_modules are compiled against Atom's v8
# headers.
#
# Some useful grunt options are:
#   --instal-dir
#   --build-dir
#
# To keep the various directories straight, here are what the various
# directories might look like on MacOS
#
# tmpDir: /var/folders/xl/_qdlmc512sb6cpqryy_2tzzw0000gn/T/ (aka /tmp)
#
# buildDir    = /tmp/edgehill-build
# shellAppDir = /tmp/edgehill-build/Edgehill.app
# contentsDir = /tmp/edgehill-build/Edgehill.app/Contents
# appDir      = /tmp/edgehill-build/Edgehill.app/Contents/Resources/app
#
# installDir = /Applications/Edgehil.app
#
# And on Linux:
#
# tmpDir: /tmp/
#
# buildDir    = /tmp/edgehill-build
# shellAppDir = /tmp/edgehill-build/Edgehill
# contentsDir = /tmp/edgehill-build/Edgehill
# appDir      = /tmp/edgehill-build/Edgehill/resources/app
#
# installDir = /usr/local OR $INSTALL_PREFIX
# binDir     = /usr/local/bin
# shareDir   = /usr/local/share/edgehill

# Add support for obselete APIs of vm module so we can make some third-party
