If you do this:
defaults write com.apple.InterfaceBuilder \
VersionControlDirectory "(Build, CVS, .svn)"

it will let XCode know to ignore these folders from a SCM perspective.

cvs ls ${modulelist} 2> ${modulelist}.txt
cat ${modulelist}.txt | awk 'BEGIN { FS = ": " } ; { print $2 }'

CVS is a free and widely used Source Code Management (SCM) application.

Handy tips
To use "CVS -F ...

You need to have unix line endings on the file!

Handy scripts

If you want to list all tags for a file you can do something like this on a standard unix shell:
cvs -z9 -q rlog -h $fileName | sed -n -e '/^\W.*[A-Z|a-z]/p' | sed -e 's/:.*$//' | sed -e 's/\W*//'

If you want to see what items that are not "Up-to-Date" you can do something like this:
cvs status | grep "Status:" | grep -v "Up-to-date"
It will pull all the "Status:" lines of the output and then show only the ones that are not "Up-to-date".

For windows you will have to replace the grep with findstr such as this:
cvs status | findstr "Status:" | findstr /v "Up-to-date"
