You need to get the help files for the BLAST and Retreive servers at NCBI.
You may also find NEntrez useful. This information is available via
anonymous FTP. FTP to ncbi.nlm.nih.gov and login as anonymous, using your
email address as a password. Browse through the directories for BLAST and
download the help file. Do the same for Retreive and Entrez (Network). If
you need more help, email me.
