+# http_require
+
+## Idea
+
+The idea is very simple:
+test.rb:
+    # this will download bar.rb and eval its content.
+    require "http://foo.com/bar.rb"
+
+If a remote file (or one of its local dependencies) requires something that
+can't be found locally, it will try to find it remotely from the same location
+as the parent.
+
+## Example
+
+http://example.com/test/foo.rb:
+    # this will load "http://example.com/test/foo/bar.rb"
+    # if "foo/bar" is not available locally
+    require "foo/bar"
+
+## Homepage
+
+You can find the latest sources on [github]:(http://github.com/astrails/http_require)
+
+## Installation
+
+    sudo gem install astrails-http_require --source http://gems.github.com/
