Alias modules are the simplest kind of module:
-a aliases...checkout
creates all intermediate directories in the working
directory, just as if the path had been specified
explicitly in the cvs arguments.
For example, if the modules file contains:
amodule -a first-dir
then the following two commands are equivalent:
$ cvs co amodule
$ cvs co first-dir
and they each would provide output such as:
cvs checkout: Updating first-dir
U first-dir/file1
U first-dir/file2
cvs checkout: Updating first-dir/sdir
U first-dir/sdir/sfile
