 Curry Tools
 ===========
 
-This directory contains various tools for Curry
+This directory contains some base tools for Curry
 that are used by different Curry systems, like PAKCS or KiCS2.
 
 Currently, it contains the following tools:
 
-`addtypes`:
-A tool that adds type signatures to a given Curry program.
-
-`analysis`:
-A directory containing various analyses for Curry programs.
-These are used in the `CASS` and `currydoc` tools.
-
-`browser`:
-A tool to browse through the modules and functions of a Curry program,
-show them in various formats, and analyze their properties.
-
-`casc`:
-A style checker for Curry programs.
-
-`CASS`:
-This directory contains the implementation of the
-Curry Analysis Server System, a generic and distributed analysis system
-for Curry programs.
+`cpm`
+This repository contains the Curry package manager (CPM)
+with the main executable `cypm`.
+CPM is a tool to distribute and install Curry packages.
+It can be used to download further Curry libraries and applications.
 
 `cpns`:
 This directory contains scripts and executables for the
 Curry Port Name Server (CPNS) which is responsible for managing the
 symbolic names assigned to the named sockes and ports on a local machine
-(see libraries `NamedSocket` and `Ports` for more details).
-
-`curry2js`:
-A compiler for Curry into JavaScript programs used in the
-generation of web user interfaces (WUIs).
-
-`currycheck`:
-A property test tool for Curry programs.
-
-`currydoc`:
-A documentation generator for Curry programs.
-
-`currypp`:
-A preprocessor for Curry programs implementing integrated code,
-default rules, deterministic functions, and dynamic contract checking.
-
-`currytest`:
-A test tool for Curry programs.
-
-`ertools`:
-Compilers to translate database (ER) models
-into Curry programs providing high-level access to relational databases.
-
-`importcalls`:
-A tool to show all calls to imported functions in a module.
+(see library `NamedSocket` for more details).
 
 `optimize`:
 The implementation of optimization tools cor Curry,
 in particular, a transformation tool to replace Boolean equalities
 by unification constraints.
 
-`runcurry`:
-The implementation of the command `runcurry`.
-
-`spicey`:
-The implementation of Curry's web framework Spicey.
-
-`verification`:
-This directory contains tools to support the verification of
-Curry programs, e.g., a translator of Curry programs into Agda.
-
 `www`:
 This directory contains scripts and executables for the
 event handler server that is required to execute dynamic web
 pages implemented with the libraries HTML or WUI.
-
-`xmldata`:
-This directory contains a tool to generate conversion functions
-between data types and XML representations. The corresponding
-tool is called by the command `data2xml` in the binary directory
-of the Curry system.
