+Heroku buildpack: curl with sftp (libssh2) support
+==================================================
+
+This is a [Heroku buildpack](http://devcenter.heroku.com/articles/buildpacks) that replaces the Ubuntu default `curl` and `libcurl` with a latest compiled version including ssl and libssh2 packages.
+Purpose for this addition is to enable using sftp with curl from PHP application via autheticating Proxy like QuotaGuard or Fixie.
+
+Usage
+-----
+
+See Heroku's documentation on [multiple buildpacks](https://devcenter.heroku.com/articles/using-multiple-buildpacks-for-an-app).
+
+Example usage for a PHP app:
+
+    $ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-php.git
+    $ heroku buildpacks:add https://github.com/frcade/heroku-buildpack-curl-libssh2.git --index 1
+    $ git push heroku master
+    ...
+
+You can verify the installation using the following command:
+
+    $ heroku run "curl --version"
