It's pretty easy. You just have to have the Wharf exist under several different names, and then configure each of them using its name. For example, if you make a link to Wharf called MyWharf (type man ln if you don't know how to make links), you would use lines like these in your /GNUstep/Library/AfterStep/wharf file :
*MyWharfAnimate
*MyWharf "label" Icon.xpm Exec "something" something
Same for the Pager.
Note: Apparently, due to the way the Wharf configuration file parser works, links with names like Wharf2 (i.e. the same original name with characters appended to it) will not work: the parser will think you are referring to the original module and will get confused. You have to give each link a distinctive name.
First, you need AfterStep 0.98 beta 4 or later. These version have the MaxSwallow option. Then, add a command such as this to the wharf file or line (depending on whether you use .steprc):
*Wharf asclock nil MaxSwallow "asclock" asclock -12 -shape &
You can omit the `-12' to be in 24 hour time.
When installing, after executing configure, asclock configure should be lauched by default. Otherwise, go to the modules/asclock directory and do the following:
