Is there any 'alias' feature in SVN like we have in CVS?

I am migrating to SVN from CVS. In CVS I have various aliases defined in CVSROOT/Modules file. That helps me to checkout multiple directories in one go.

For example:

Defined alias in CVSROOT/Modules file as below

=----------------------------------------开发者_JAVA百科----------------------------------=

my_alias /dir1 /dir2 /dir3 /dir4 /dir5 /dir6

=--------------------------------------------------------------------------=

So my checkout comamnd is optimized from

$cvs co /dir1 /dir2 /dir3 /dir4 /dir5 /dir6

to

$cvs co my_alias

I want to know if there is any similar feature in SVN.

Maybe you are looking for svn:externals

May be you should think about combine them into a single folder instead of different ones.
