Confused about links

[Rod R. <ro...@su...>]

I just installed sql-ledger 1.4.2 on a Slackware box -- it's been a 
while since I last looked at it and I'm very impressed with its 
progress.

Here's my question: what is the "Link" column for in the 
chart-of-accounts list, and what sets its value?  Also when I add a 
part or service, what roles will the "Link Accounts" choices play?

Thanks...
