[cells-devel] What should I do with JPGs and GIFs?

[Bob Hutchison]

We put binaries into CVS all the time. Don't really have much of a 
choice. There are some catches:

1) you have to use the -kb flag or set up CVS to automatically treat 
some files as binary. This is done in the cvswrappers file in CVSROOT 
(check it out and use CVS to manage it).  Part of the 'generic' bits of 
our cvswrappers file looks like:

*.jar -k 'b'
*.gif -k 'b'
*.jpg -k 'b'
*.png -k 'b'
*.zip -k 'b'
*.gz -k 'b'
*.tar -k 'b'
*.tgz -k 'b'
*.pdf -k 'b'
*.bz2 -k 'b'
*.bz -k 'b'
*.z -k 'b'
*.doc -k 'b'
*.ser -k 'b'

2) CVS won't store differences between versions, it stores the whole 
thing. This can chew up disk space.

3) A consequence of 2) is that you can get nasty behaviour going on 
with multiple people checking in changes (net effect is that you don't 
get very good control over these binary files with CVS). You have to 
manually (as far as I know) lock and unlock the file to prevent the 
problems.

Cheers,
Bob
