question on INSTALL file

[paulwheeler]

There is a file that is often included in packages for compiling and
installing software. The file is: "INSTALL". It is NOT the "install"
file that everyone uses as part of the configure, make process.

It appears to be a file that the developer can modify to give specific
instructions to the user. I do not think it is needed to compile the
software, but is just for the user.

Can anyone tell me for sure whether this is used by the system, or is
just information for the user?

Thank you

Paul
