Compiling

Just unpack the sources and type "make" it. It's currently a very simple program and this should simply create a binary called 'snapshot2cvs'.

Using

First of all, unpack all your snapshots (or at least two of them) into separate directories. I'll show the usage by creating a CVS version of the linux kernel, versions 2.4.0 to 2.4.10:

# for VERSION in 0 1 2 3 4 5 6 7 8 9 10; do

#>      tar xjf /path/to/linux-2.4.${VERSION}.tar.bz2
#>      mv linux linux-2.4.${VERSION}
#>      done

Now, you've got four kernel source trees on your hard drive. The very first version ever is completely empty, so let's start feeding your CVS repository with an empty directory:

# mkdir empty_dir
# cd empty_dir
# cvs import -m "Initial empty import" linux foo bar # cd ..
# cvs co linux
# cd linux

Now, you've got an empty "linux" directory, which is at least under CVS control. Now let's feed in all the linux versions, but keep in mind that for now all pathes need to be absolute (I'm not perfect:-)

# snapshot2cvs /path/to/empty_dir /path/to/linux-2.4.0 /path/to/linux # cvs ci -m "Importing linux kernel versin 2.4.0" # cvs tag v_2_4_0

Now let's feed in all other versions:

# for OLDERVERSION in 0 1 2 3 4 5 6 7 8 9; do

#>      snapshot2cvs    /path/to/linux-2.4.${OLDERVERSION}              \
                        /path/to/linux-2.4.$(expr ${OLDERVERSION} + 1)  \
                        /path/to/linux
#>      cvs ci -m "Importing linux kernel version 2.4.`expr ${OLDERVERSION} + 1`"
#>      cvs tag "v_2_4_`expr ${OLDERVERSION} + 1`"
#>      done

That's it. You should now have a nice repository with all required files:-)

Problems

All files are checked in with the "-ko" option. I wanted to keep all the "$xxx $" strings. Maybe I should make this an option:-)
It lstat()s files all over all. That's not that fine...
There are better ways to achieve the result, but my one is at least working for me
Sorting all files/directories is less than good. It was written about 5 o'clock in the morning and I should rewrite it (using a better sorting algorithm ot just libc's qsort()...
I copy too many files (some are copied twice)
I call 'cp' to copy a file instead of copying it myself

Goodies

It seems to work
