+# SYNOPSIS
+#
+#   AX_LIB_SQLITE3([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+#   Test for the SQLite 3 library of a particular version (or newer)
+#
+#   This macro takes only one optional argument, required version of SQLite
+#   3 library. If required version is not passed, 3.0.0 is used in the test
+#   of existance of SQLite 3.
+#
+#   If no intallation prefix to the installed SQLite library is given the
+#   macro searches under /usr, /usr/local, and /opt.
+#
+#   This macro calls:
+#
+#     AC_SUBST(SQLITE3_CFLAGS)
+#     AC_SUBST(SQLITE3_LDFLAGS)
+#     AC_SUBST(SQLITE3_VERSION)
+#
+#   And sets:
+#
+#     HAVE_SQLITE3
