I believe Kit Baum is out of town, so I'll attempt
a reply on his behalf (also as original joint author
of -ssc-.)
The important detail here is not only the difference
between SSC and -ssc-. That's clear: SSC is an archive,
which as it happens includes both Stata and non-Stata
material, while -ssc- is a Stata command. Also, and
very importantly, SSC came first, and follows its own
rules. It's, emphatically, not controlled by StataCorp,
although I think it's fair to say they are very happy
that it exists. -ssc- is just a tool for accessing SSC's
Stata material. It's an official Stata command.
The detail here is that there is not a one-to-one
correspondence between SSC resources and possible -ssc-
downloads of Stata programs or help files.
I looked to see how -ssc- is written up. The help starts:
"-ssc- works with packages (and files) from the
Statistical Software Components (SSC) archive,
often called the Boston College Archive, and
provided by http://www.repec.org"
In this particular case, the package is just the
file clarify.pkg whose contents you see with
-ssc desc clarify-. There are no further
files corresponding to the -clarify- entry.
The entry is there as a pointer to Gary King's stuff.
-findit clarify- also gets you there, as Friedrich points
out. As many people know, Gary's group provides
resources from his own webpages.
There are a few such entries on SSC, intended
to be helpful rather than the reverse.
In short, -ssc- works exactly as advertised, but
there is no absolute rule that a package need
include Stata .ado and/or .hlp files.
