 #### RefC
 
-* Adds support for `CFLAGS`, `CPPFLAGS`, and `LDFLAGS` to facilitate building on
-  systems with non-standard installation locations of libraries (e.g. GMP).
-  Versions of the flags with the `IDRIS2_` prefix can also be used and take
-  precedence.

+# This test checks to make sure that Idris2's command line handling for the RefC backend is correct.
+# It checks that:
+#   1) Idris2 correctly finds `CFLAGS` and `LDFLAGS` in the environment,
+#   2) The values in `CFLAGS` and `LDFLAGS` are separated correctly to be passed to the compiler
+#
+# (1) is achieved by compiling a c library (`externalc`) in a separate folder, and then explicitly
+# pointing the compiler to the header files (with `-I./library/`) and shared library (with `-L./library`)
+# and requesting that libexternalc.{so,dylib,dll} is linked (with `-lexternalc`). We additionally point the
+# dynamic library loader to the correct location with `DYLD_LIBRARY_PATH`.
+#
+# (2) is achieved by passing multiple options, separated by spaces, in each of `CFLAGS` and `LDFLAGS`.
+# These options are `-O3` for the c flags, and `-Wl,-pie` for the linker flags. They do not change the
+# semantics of the resulting code (`-O3` simply optimises it more, and `-Wl,-pie` emits position
+# independent code in the final executable), but do check that we correctly split up the environment
+# variables when we pass them to the C compiler.
