st: Identify and install user ado's (was: Re: -firstdigit- available from SSC)

["Ben Jann" <ben.jann@gmail.com>]

A program that finds and installs all user-ado's (from SSC, say) does
not exist to my knowledge. It could be easily written, but I think
there is not much point in such a program because there is so much
stuff online, you would not want all that on your system at the time.

If you have to switch systems and want to reinstall the user ado's
that were on your old system, then have a look at -adolist- (type -ssc
describe adolist-). The procedure is to type

. adolist store <pgklist>

on the old system, copy the stored package list file to Stata's
working directory on the new system, and then type

. adolist install <pgklist>

on the new system to install the package from the net. <pgklist> is a
name for the package list of your choice.

Hope this helps,
ben
