Description

We should add the following forms to the action language:

• (with-stdin-from <file> <action>)
• (pipe-stdout <action1> <action2> ...)
• (pipe-stderr <action1> <action2> ...)
• (pipe-outputs <action1> <action2> ...)

Pipes should be implemented with temporary files, to make things simpler and more portable.

Implementation

The action language is defined in src/action_intf. One should add the new actions and then follow compilation errors to implement them.

The Future.run* functions will need to be adapted to support stdin redirection.
