SSC stands for Statistical Software Components archive, a.k.a. Boston College
Archive a.k.a. RePeC.  SSC has become the premier download site for
user-written software on the web.  If you don't already know about the -ssc-
command, type -help ssc-.  -ssc- is easy to use.  If you wanted to install the
package named -estout-, you could type

        . ssc install estout

and, if you later wanted to uninstall it, you would type 

        . ssc uninstall estout

Anyway, by default -ssc whatshot- lists the ten most popular packages, 
but you can specify the number to list:

        . ssc whatshot, n(20)
        <output omitted>

Type -ssc whatshot, n(.)- to list all packages.  If you wanted to see
the ten most popular packages by Nickolas Cox, you type

        . ssc whatshot, author(cox)

You can combine the -n()- and -author()- options.

The list is updated monthly and is based on a 3-month moving average.

P.S.  Be careful about putting -ssc whatshot- on the subject line of email.
      We have already discovered that most email filters give "whatshot" a 
      high spam score.
