Explain @(#)cshrc 1.11 89/11/29 SMI

What does ' @(#)cshrc 1.11 89/11/29 SMI ' mean?
Can someone please deconstruct and explain the parts?
Code:
# @(#)cshrc 1.11 89/11/29 SMI

It is at the top of a the .cshrc of a new Solaris account I am working on.
I am familiar with using the first line of a script for setting the program/shell to use. Example: #!/bin/csh or #!/bin/sh or #!/ben/perl.
I am also familiar with leaving the first line blank or adding a comment. For .cshrc (opposed to my_script.csh) I just start with a # comment line.

Searching the internets, I see lots of examples of .cshrc posted that begin with this line, but I have not found anybody who explains what it is doing or where it comes from. The best I tell, it is just a comment. But why does it appear at the beginning of so many .cshrc files?

NAME
resize - set TERMCAP and terminal settings to current xterm window size SYNOPSIS
resize [ -u | -c ] [ -s [ row col ] ] DESCRIPTION
Resize prints a shell command for setting the TERM and TERMCAP environment variables to indicate the current size of xterm window from which the command is run. For this output to take effect, resize must either be evaluated as part of the command line (usually done with a shell alias or function) or else redirected to a file which can then be read in. From the C shell (usually known as /bin/csh), the follow- ing alias could be defined in the user's .cshrc: % alias rs 'set noglob; eval `resize`' After resizing the window, the user would type: % rs Users of versions of the Bourne shell (usually known as /bin/sh) that don't have command functions will need to send the output to a tempo- rary file and the read it back in with the ``.'' command: $ resize > /tmp/out $ . /tmp/out OPTIONS
The following options may be used with resize: -u This option indicates that Bourne shell commands should be generated even if the user's current shell isn't /bin/sh. -c This option indicates that C shell commands should be generated even if the user's current shell isn't /bin/csh. -s [rows columns] This option indicates that Sun console escape sequences will be used instead of the VT100-style xterm escape codes. If rows and columns are given, resize will ask the xterm to resize itself. However, the window manager may choose to disallow the change. Note that the Sun console escape sequences are recognized by XFree86 xterm and by dtterm. The resize program may be installed as sunsize, which causes makes it assume the -s option. The rows and columns arguments must appear last; though they are normally associated with the -s option, they are parsed sepa- rately. FILES
/etc/termcap for the base termcap entry to modify. ~/.cshrc user's alias for the command. SEE ALSO
