 ExCmd is an Elixir library to run and communicate with external programs with back-pressure mechanism. It makes use os provided stdio buffer for this.
 
-Communication with external program with [Port](https://hexdocs.pm/elixir/Port.html) is not demand driven. So it is easy to run into memory issues when the size of the data we are writing or reading from the external program is large. ExCmd tries to solve this problem by making better use of os provided stdio buffers and providing demand-driven interface to write and read from external program. It can be used to stream data through an external program. For example, streaming a video through `ffmpeg` to serve a web request.
