++ libglacier
+
+The underlying C libraries for the Glacier package manager
+
++ Rationale
+
+Glacier has been written in Bash since its conception. For obvious reasons, this is terrible for portability.
+While writing an entire library for a project that's been in the works for a year at this point will take
+much more time, it should futureproof Glacier and make it easier to deploy and test.
+
++ Usage
+
+	#include <glacier_log.h>
+	#include <glacier_config.h>
