In wwdemo.prg, there is a #INCLUDE WCONNECT.H. Is the utility of including that file here for the purpose of recognizing those lines which appear later on the code?

#DEFINE HOMEPATH "/wconnect/"
#DEFINE HOMEPAGE HOMEPATH+"default.htm"
#DEFINE BACKIMG  ""
#DEFINE PAGEFOOT ...

As I took that sample when building my project, I was wondering if I could get ride of the include command as well as those lines.
