| 9 | .SH DESCRIPTION |
---|
| 10 | .I Xcluster |
---|
| 11 | displays a map of the MIT campus and marks the location of Project |
---|
| 12 | Athena public clusters with an "X". The user can click |
---|
| 13 | on the map, and information about the cluster nearest the mouse-click |
---|
| 14 | is displayed. The clusters are also listed in a row of buttons below |
---|
| 15 | the map, and the user may click one of those buttons instead. |
---|
| 16 | .PP |
---|
| 17 | Once a cluster has been selected, a circle is drawn around it so that it |
---|
| 18 | is more easily spotted. |
---|
| 19 | .I Xcluster |
---|
| 20 | then contacts a server that tracks the number of workstations |
---|
| 21 | free and in-use for each cluster, and displays that information for the |
---|
| 22 | cluster chosen. Printer status for that cluster is also displayed, as |
---|
| 23 | well as phone number(s), where available. |
---|
| 24 | .PP |
---|
[12492] | 25 | Xcluster can also run in a non-interactive mode, where it cycles |
---|
| 26 | through the clusters automatically. It can also be made to cycle |
---|
| 27 | through a series of foreground and background colors, to prevent |
---|
| 28 | screen burn-in on the dedicated xcluster machines that run this |
---|
| 29 | program all the time. |

| 41 | .TP 21 |
---|
| 42 | .B \-auto time |
---|
| 43 | cycle through the clusters, selecting each for |

[12492] | 49 | .TP 21 |
---|
| 50 | .B \-zoom |
---|
| 51 | causes the campus map to be moved and resized to the largest size such |
---|
| 52 | that all of the clusters still fit. |
---|
| 53 | .TP 21 |
---|
| 54 | .B \-warp |
---|
| 55 | causes the pointer to be warped to the top, left corner of the screen |
