LinCVS uses icons to show the current state of dirs in a cvs project tree. 
A certain state found deep down the hierarchy affects all its parent 
folders, so you have an overview of the project state without itering 
through all dirs. The icons show the dir folder with some completion signs.
The meaning of these signs are as follows:

1. A green star: Folder contains file(s) unknown to the cvs repository
2. A blue star: Folder contains file(s) that are cvs-registered and modified
3. A red star: Folder contains file(s) where a cvs command was already run on, 
   and now changes need to be commited (add/remove)
4. A warning sign: Folder contains file(s) that need a: patch/merge/checkout
5. A red warning cross: Folder contains file(s) with a conflict. 
   Please note that files are marked as conflict until the conflict is 
   resolved and the file commited.

Addon: Blue folders are a substitute for directories that are existing in the 
       repository but not jet checked out/updated. You will only find them when 
       running query update/query update (all). They are refered to as 
       'virtual dirs' in the whatsthis/docu.
