[davidw]: It would be nice to see at least a simple example included for all Tcl man pages (or at the very least point to another page including an example).

Here is the current state of things:
----
'''Files with examples:'''

'''Files without examples:'''

These are automatically generated (script below).  Some of these do have examples, such as msgcat and tcltest.  Others sort of do, but a functional bit of code that runs and demonstrates the command is always welcome.

'''Exception List''': The list of files that really do have (good) examples: binary.n msgcat.n tcltest.n.

and the list of files that describe commands that are too simple to really need examples (or that have them elsewhere): cd.n close.n

Adding an example doesn't take much time, and lots are already available on the wiki.  All you have to do is submit a patch to sourceforge.  The man page markup looks like this:

 .SH "EXAMPLES"

 A time server:

 .CS
 proc Server { channel clientaddr clientport } {
     puts "Connection from $clientaddr registered"
     puts $channel [clock format [clock seconds]]
     close $channel
 }

 socket -server Server 9900
 vwait forever
 .CE


I used this code to check:

 package require fileutil
 package require struct

 foreach res [fileutil::grep ".SH.*EXAMPLE" [glob *.n]] {
     lappend examplefiles [lindex [split $res :] 0]
 }
 set examplefiles [lsort $examplefiles]

 set allfiles [lsort [glob *.n]]
 set noexamplefiles [lsort [struct::set difference $allfiles $examplefiles]]

 puts "Files with examples: $examplefiles"
 puts ""
 puts "Files without examples: $noexamplefiles"

[DKF]: Remember that some [Tk] docs need examples as well, though I'd tend to say not the widgets, as they're better demonstrated as part of the general [widget] demo.
