+# Native libraries built as part of the rust build process
#
-# This is not really the right place to explain this, but
-# for those of you who are not Makefile gurus, let me briefly
-# cover the $ expansion system in use here, because it
-# confused me for a while! The variable DEF_RUNTIME_TARGETS
-# will be defined once and then expanded with different
-# values substituted for $(1) each time it is called.
-# That resulting text is then eval'd.
+# This portion of the rust build system is meant to keep track of native
+# dependencies and how to build them. It is currently required that all native
+# dependencies are built as static libraries, as slinging around dynamic
+# libraries isn't exactly the most fun thing to do.
#
-# For most variables, you could use a single $ sign. The result
-# is that the substitution would occur when the CALL occurs,
-# I believe. The problem is that the automatic variables $< and $@
-# need to be expanded-per-rule. Therefore, for those variables at
-# least, you need $$< and $$@ in the variable text. This way, after
-# the CALL substitution occurs, you will have $< and $@. This text
-# will then be evaluated, and all will work as you like.
+# This section should need minimal modification to add new libraries. The
+# relevant variables are:
#
-# Reader beware, this explanantion could be wrong, but it seems to
-# fit the experimental data (i.e., I was able to get the system
-# working under these assumptions).

-# Hack for passing flags into LIBUV, see below.
