Carsten,
CVS can do this via module aliases.
This is best explained with an example: say you are starting work on
'big_project', which consists of two modules: big_project_client and
big_project_server. You wish to include a couple of useful Perl modules
from the in-house utilites module. Here's one approach:
First, checkout your repository's 'modules' file:
cvs co CVSROOT/modules
Create some aliases in this file for 'big_project':
# Create a module alias for the perl modules we need
# Alias name module to use files to extract
perl_modules utilities/perl/lib Module1.pm Module2.pm
#
# Create an alias for big_project, using "ampersand aliases"
big_project &big_project_client &big_project_server &perl_modules
Commit this back to your repository.
Now when we checkout big_project, we get the following directory
structure:
big_project/big_project_client
big_project/big_project_server
big_project/perl_modules
and big_project/perl_modules will contain
big_project/perl_modules/utilities/perl/lib/Module1.pm
big_project/perl_modules/utilities/perl/lib/Module2.pm
The Cederqvist manual has more on module aliases at:
