You might also experiment with defining the sub-modules in the "modules"
file.  If you give them a descriptive name, and point that name to a
sub-module, it should work fine.

We had investigated going this route for a few of our modules but gave
it up as our modules (projects) are added to frequently.  It sounds like
your products are a bit more static, and you may benefit from this

So, your modules file might contain:
1920-Mk6e-All            1920-Mk6e
1920-Mk6e-FirmwareOnly   1920-Mk6e/Z00-Firmware
1920-Mk6e-BootloaderOnly 1920-Mk6e/Z01-Bootloader

1680-Mk6-All             1680-Mk6
1680-Mk6-FirmwareOnly    1680-Mk6/Z00-Firmware
1680-Mk6-BootloaderOnly  1680-Mk6/Z01-Bootloader
1680-Mk6-ChechsummerOnly 1680-Mk6/Z03-Chechsummer



When you "fetch list" in Tortoise, you should see a combination of the
"ls" command, and the contents of the modules file, so (alphabetical

Keep in mind that if you added a new product or Z series folder, you'd
have to manually edit the modules file - but that can be done by anyone
on the client side with the correct permissions.

I would urge you to only divide items among repository lines when
necessary.  Keep in mind that EACH repository can be configured
differently, and requires server work to set up.  Here, we had set a few
repositories and only two are regularly used - and anytime something is
put in a repository that almost no one uses, half the users don't know
how to find it.

Generally, repositories are more difficult to manage and less flexible
than modules.  For instance, if you decide you want a common set of
libraries that lives in a module, and you want that to be a
automatically checked out into a subfolder of specific modules, you can
do that using ampersand (&) modules as long as both reside in the same

For instance, if you had a "library" module and "bootloader" and
"firmware" subdirectories (or sub-modules) within that, your modules
file could like this (doing the syntax from memory):
BootLoaderLibrary     Library/BootLoader
FirmwareLibrary       Library/Firmware

1920-Mk6e-FirmwareOnly   1920-Mk6e/Z00-Firmware   &FirmwareLibrary
1920-Mk6e-BootloaderOnly 1920-Mk6e/Z01-Bootloader &BootLoaderLibrary

And you'd get FirmwareLibrary as a subdirectory to
1920-Mk6e-FirmwareOnly after checkout.  Not possible if they're in
different repositories.

The primary thing we use the second repository for is non-program admin
type files that are handy to have in CVS.


The major difference between a thing that might go wrong and a thing
that cannot possibly go wrong is that when a thing that cannot possibly
go wrong goes wrong, it usually turns out to be impossible to get at or

Excuse me kinda hijacking this thread

Bo (or anyone else who would like to comment),

I have read a few CVS type docs and I am a little confused as to how I
should set up our system. We have a number of embedded products with
fairly different versions of code. Each product can have more than one
distinct section of software though.

e.g. we have one product called 1920-Mk6e that currently has two
distinct sections of code: Z00-Firmware and Z01-Bootloader.

Likewise there is another device called 1680-Mk6 which has two sections
named the same and then some more like Z03-Checksummer.

As we only have around 10-15 devices, I was initially planning on
creating separate repositries (albeit on the same server) for each
project (i.e. repositries called 1920-Mk6E, 1680-Mk6. Then have each
code section (Zxx-abcdef) as a module. If I had everything under one
repositry using the device name as the module, checking out individual
(Zxx-abcdef) sections is possible but not as simple.

I am trying to use TortoiseCVS (for simplicity over command line -
otherwise the developers won't use it) and it doesn't easily support
directories below modules. i.e. the Fetch List button when doing a
checkout only gives the modules in the repositry and nothing lower. _IF_
I know the name of the lower directories I can add them only they will
be checked out. It's not that simple to use though and knowing the guys
around here they will whinge and complain.

Suggestions as to how I should implement things? I am sure others have
faced a similar if not an identical situation
