Re: st: Problems with eststo, stata versioning

[Nick Cox <njcoxstata@gmail.com>]

-eststo- is a user-written program. Updating or upgrading your  
installation of Stata makes absolutely no difference to any  
installations of user-written programs, which remain entirely your own  
responsibility. However, Stata does provide -adoupdate- as a  
convenience command to help in maintaining your collection of user- 
written add-ons.
