There is a particular web page that I would like to watch and have an

that for Windows but so far have not met with success finding a
program for Linux. Freshmeat and Sourceforge both had old programs
that appear to no longer be available. Anybody else out there doing this?
I guess it would be feasible to write a C program using a socket to
access the site in question, and read its contents in raw material form
(with all the HTML tags). This is really no big deal, I have done this
more than once. It is also a simple task to write a program stripping
the HTML input of all its HTML tags, leaving you with the naked
information. This could further be compared to the contents of a file in
which you have stored the previous information on the same web-page, and
the program could set up a flag and notify you if there are changes in
the items that you are watching. This C-program could be a cron-job
starting at regular intervals, or you could use the sleep function, and
let it wake up to perform its task at regular intervals at your convenience,
