Letters at beginnings of columns of svn output

Where is this documented? I sometimes see letters I don't know, such as
"G", what is that for - and these outputs may differ from command to
command. Also the column in which a letter appears is significant.

Can someone please point me to a document where this is explained? It's
not in the manual except for the status command.

Thanks
