Constructor Details

- (CvsAdapter) initialize(url, root_url = nil, login = nil, password = nil, path_encoding = nil)

Guidelines for the input:

url -> the project-path, relative to the cvsroot (eg. module name)
root_url -> the good old, sometimes damned, CVSROOT
login -> unnecessary
password -> unnecessary too
