+an association of independent craftspeople.  A guildhall is where they meet.
+This Guildhall aims to make a virtual space for Guile wizards and journeyfolk
+to share code.
+
+On a practical level, Guildhall lets you share Scheme modules and programs
+over the internet, and install code that has been shared by others.  Guildhall
+can handle dependencies, so when a program requires several libraries, and
+each of those has further dependencies, all of the prerequisites for the
+program can be installed in one go.")
