XWatch can be obtained at the ftp site ftp.icce.rug.nl, in the directory /pub/unix, as the file xwatch-X.YY.tar.gz.
X.YY is the version number, e.g., 1.00. This site is the primary site,
so check here for new versions.
To unpack the archive, change-dir to your `sources' directory (e.g.,
/usr/local/src) and type
tar xvzf /where/ever/you/put/it/xwatch-X.YY.tar.gz
Next, change-dir to the unpacked subdirectory xwatch and check there.
You will find a subdirectory src with the full sources.
