+# capp_env
+
+`capp_env` is a simple virtual environment tool for Cappuccino.
+
+
+## Usage
+
+To create a virtual environment:
+
+    capp_env -p /path/to/the/env
+
+This will create
+
+    /path/to/the/env
+        /bin
+        /build
+        /sources # if you want to put your sources here, but it is optional
+        /narwhal
+
+It will download the latest `cappuccino_base`, put it in `narwhal` and will create an `activate` file in `/path/to/the/env/bin`
+
+Then you can activate this environment by doing:
+
+    source /path/to/the/env/bin/activate
+
+your current `PATH` will be updated to look for `jake` and `capp` and all the tools from `/path/to/the/env/narwhal/bin`, and will set `CAPP_BUILD` to be `/path/to/the/env/build`.
+
+From now on, you can clone the Cappuccino sources, (in `sources` for instance) and do
+
+    jake install
+
+If you install the Cappuccino source while in an virtual env, all the tools will use the debug version that you just built (for instance, `nib2cib` will be used from `/path/to/the/env/build/Debug/CommonJS/cappuccino/bin/nib2cib`)
+
+
+## Deactivate
+
+Just close the current terminal, or run
+
+    deactivate
+
+
+## TODOs
+
+    - let a chance to select the current cappuccino base version to download
+    - find a way to make XcodeCapp to use these environements
