# Create a set of standard rules for a project such that:

# - The component depends on its Makefile.

# - "build-$(component)" is an alias for "$(component)".

#

# Parameters:

#

# $1 - Directory component lives in.

# $2 - Name of component.

#

# Note: The "clean" and "vendor" rules are the "odd one out" - they only

# depend on the Makefile. This ensure that running them won't first try

# to build the project.
