+This is the INSTALL file for the parvel distribution.
+
+This package uses OASIS to generate its build system. See section OASIS for
+full information. 
+
+Dependencies
+============
+
+In order to compile this package, you will need:
+* ocaml
+* findlib
+* lwt
+* monad_io
+* substrings
+* cadastr
+
+Installing
+==========
+
+1. Uncompress the source archive and go to the root of the package
+2. Run 'ocaml setup.ml -configure'
+3. Run 'ocaml setup.ml -build'
+4. Run 'ocaml setup.ml -install'
+
+Uninstalling
+============
+
+1. Go to the root of the package 
+2. Run 'ocaml setup.ml -uninstall'
+
+OASIS
+=====
+
+OASIS is a program that generates a setup.ml file using a simple '_oasis'
+configuration file. The generated setup only depends on the standard OCaml
+installation: no additional library is required.
