 # Bisquay
 
+A quixotic compendium of code for audio-processing applications
+written in the [Standard ML](https://smlfamily.github.io/) programming
+language.
+
+ * Bisquay is *quixotic* because SML is not an obvious choice of
+language for this purpose and there is no existing library of
+applicable code to build on. As much as anything, it is an effort to
+escape the rat race.
+
+ * Bisquay is a *compendium* because this repository contains (almost)
+no code, just a [Repoint](https://github.com/cannam/repoint) manifest
+that defines a multitude of modules to pull in as
+subdirectories. Several of these modules are third-party, or were
+originally written for other purposes, while others (with names
+beginning `bsq`) were written specifically for this.
+
+All Bisquay code is licensed under a BSD/MIT or equivalent licence.
