20 #
21 # ======================================================================
22 # Usage:
23 #
24 # This script compiles `simple' SuperCollider plugins, i.e. plugins that
25 # consist of only one source file. Source files may be C++ implementations or
26 # a Faust[1] DSP specification.
27 #
28 # Source file paths are passed either in a file (specified with the
29 # PLUGIN_SOURCES option) or via standard input.
30 #
31 # E.g., when source file paths are in a file called sources.txt:
32 #
33 # $ sc-build-plugins PLUGIN_SOURCES=sources.txt
34 #
35 # Alternatively, source file paths can be passed via standard input:
36 #
37 # $ my-command | sc-build-plugins
38 #
