[GRASSLIST:10125] Polylining line segments

[Steven Gordon]

Thanks for the help on the v.patch command. That quickly merged all  
of the layers together that I needed combined.

About the v.build.polyline command...Does this command join line  
segments that share all share-able attributes?

For example, the U.S. Census Tiger road line data has attributes for  
length, node ID, street name, street type, and so forth. Because the  
attribute values are different, the v.build.polyline command must  
join segments whose attribute values can be shared (like street name)  
while ignoring attribute values that have to be unique for each line  
segment (length, ID). Is that correct?
