+LICENSE
+=======
+
+Thaw is distributed under the GPLv2 license. You can find it in a file
+called "gpl.txt" and joined with every copy of Thaw.
+
+
+COMPILATION
+===========
+
+In order to compile Thaw, you need to obtain the latest version of hsqldb.jar.
+
+Here is a link to the current (06/11/2006) version of hsqldb:
+http://switch.dl.sourceforge.net/sourceforge/hsqldb/hsqldb_1_8_0_4.zip
+
+Extract the zip, and copy "hsqldb/lib/hsqldb.jar" to "Thaw/lib".
+
+To compile:
+ $ ant
+
+To build the jar file:
+ $ ant jar
+
+To build the javadoc:
+ $ ant javadoc
+
+
+RUNNING
+=======
+
+On Unix / Linux / etc:
+$ cd lib ; java -jar Thaw.jar
+or
+$ ant run
+
+
+On Windows:
+err ... we will see that later ...
