Ftp.BRulesCorp.com
ftp.brulescorp.com is Business Rules Corp's primary tool for distributing updates and utilities. Arguably until the BR Wiki, it had served as the best source for developers to find up to date documentation.
The ftp.brulescorp.com category is used to flag articles written about files you can download from ftp.brulescorp.com.
Several of the files that are contained on the site are also documented here. Ideally their page titles are linked to by their file names on the FTP site.
