+This project is an integration test, testing various Go database
+drivers (for the database/sql package).
+
+To run these tests, in this directory, run:
+
+$ export GOPATH=$PWD
+
+... ignoring your existing GOPATH.  (This project imports all the 3rd
+party drivers here, to make things easier to track, and to enable
+local fixes while waiting for upstream.)
+
+Then:
+
+$ cd src/sqltest
+$ gotest -v
+
+or, most of the time, skipping the annoyingly long tests:
+
+$ gotest -v -short
