Re: Help or suggestions on porting to subversion

Hello Ryan,

Of course the cleanest way is to checkout the whole trunk/ and tag the
 trunk each time.
A single checkout of the whole / directory is tens of GB over a
network (non-LAN), multiply this for all the deveopers.
The solution does not scale well even if checkout with --depth is
disabled. Furthermore tagging the whole trunk each time would be make
the concept it is for pointless.

The thing we want is:
- checkout single/scattered files from different directories
- modify/commit them
- group the files and tag this group (only the files in this group).

The slow transition of reorganizing by moving the files in projects as
we modify them is basically not possible and might be confusing. Also
not every developer has an idea of all the dependencies involved when
he/she just wants to modify a single file. It's even possible that
base/common libraries will never be touched at all. Just Tto be short
there are other reasons I will not mention ..
