(c) 1992 Heiko W.Rupp hwr@pilhuhn.ka.sub.org
|
||
uusnap is a tool to display the activities of the connected
|
||
systems.
|
||
|
||
Put a file uusnap.systems in NEWCONFIGDIR (see Makefile), in which
|
||
the systems, you want to monitor are listed, one on a single line.
|
||
The sequence of the files there determine the sequence of the
|
||
listing.
|
||
|
||
At the moment it only works with taylor config and taylor dirs
|
||
|
||
compile it form the Makefile or:
|
||
cc -c -g -pipe -O -I. -I. -DNEWCONFIGLIB=\"/usr/local/lib/uucp\" uusnap.c
|
||
cc -o uusnap uusnap.o
|
||
For this, uusnap.[ch] must be in the same directory as uucp.h and so.
|
||
|
||
uusnap must have read access to SPOOLDIR/.Status in order to work.
