CAP and netatalk store files in similar, but distinct, ways. Both use the
filesystem to store the data fork. They use different methods to store the
"extra bits" of information that Macs need:
CAP stores the "finder metadata" as files in a subdirectory named
.finderinfo and stores the resource fork in a subdirectory named
.resource
netatalk stores both the finder metadata and the resource fork in a single
file in a subdirectory named .AppleDouble - the file format used includes
an AppleDouble file header. See:
http://www-sccm.stanford.edu/Students/hargrove/HFS/README-4.html
Actually, it appears to me that on linux you could move everything by
mounting the CAP directories as one HFS filesystem, the new
netatalk-style directories as another HFS, and then just copy things
over
with linux. That would be cool if it actually worked. See:
http://www-sccm.Stanford.EDU/~hargrove/HFS/
http://www-sccm.stanford.edu/Students/hargrove/HFS/README.html
for the details of how you'd have to mount the two HFS filesystems.
-----
the program mkisofs and its predecessor mkhybrid also both understand the
CAP and netatalk directory structures, so you could create an HFS CD image
or CDs (using cdrecord) and move all the CAP files to your Mac.

---install both CAP and netatalk simultaneously, and sit at a mac and move things around.
for CAP, see:

A fellow by the name of Jonathan Paisley claims to have written a C program to move files from CAP to netatalk formats. See:
http://www.umich.edu/~rsug/netatalk/archive/admins/2000/1197.html http://students.dcs.gla.ac.uk/students/paisleyj/netatalk/
The latter page has an email page asking for people to e-mail him and tell him to hurry up and post his program to do it ;-)
This would probably be the best solution.
