Makefile

## {{{--| Annotations |
# (AT) sign @ prevent make from announcing command it's going to do
# Dollar sign $ is interpreted as varible, to use it make it double $$
#
# Each line that has an un-escaped new-line is echoed to the screen and is
# passed off to a shell child process shell which then executes it. If the
# shell returns a non-zero exit value make will then generally abort any
# further processing with a warning.
#
# The ``-'' tells make to ignore any return value and to continue on to the
# next command. Disregarding return values can be set globally with either the
# ``-i'' option or the ``fake'' target .IGNORE in the Makefile.
#
# The other special character ``@'' tells make not to echo the command to
# stdout. Echoing can be disabled globally with either the ``-s'' option or the
# fake target .SILENT.
#
# Special Targets
# .DEFAULT 	Its associated actions are invoked whenever make is given a
# target that is not defined.
# .IGNORE 	Ignores all return codes from actions. Same as command-line
# option ``-l''. By default make will stop processing whenever a non-zero return
# status is received from an action.
# .SILENT 	Will not echo the action as its processed. Same as command-line
# option ``-s''. By default make will echo the action to stdout prior to
# invocation.
# .SUFFIXES 	Appends any given ``prerequisites'' to the list of suffixes
# with implicit rules. If none are given then wipe the list of suffixes.
