In notes.text of the May Day PCL, it says:
> * You probably also want to begin using a precom file for your system.
> Do this by having a file whose only contents is

> for example, for the clim system, the precom file has the one line:

> compile this file after loading and running your system for a while.
> load it before loading and running your system for a while.
> load it before loading your compiled system. A future version of this

Could someone explain to me what this precom file does?
I couldn't quite understand it from the notes.
Does it improve the performance of PCL?
Also, what does "loading and running your system for a while" mean?
Thanks in advance.
