# THe Ultimate Make Bash Script
# Used to wrap build scripts for easy dep
# handling and multiplatform support


# Basic usage on *nix:
# export tbs_arch=x86
# ./thumbs.sh make


# On Win (msvc 2013):
# C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall x86_amd64
# SET tbs_tools=msvc12
# thumbs make

# On Win (mingw32):
# SET path=C:\mingw32\bin;%path%
# SET tbs_tools=mingw
# SET tbs_arch=x86
# thumbs make


# Global settings are stored in env vars
# Should be inherited

# keep the keys in sync ... no assoc arrays on msys :/
# targ contains a target for each dep (default=empty str)
# post is executed after each thumbs dep build
