See your changes since checkout.
 > cvs diff                   

See repository changes since checkout.
 > cvs diff -D now            

See repo checkins not in your checkout.
 > cvs diff -r HEAD -r BASE   

See all the versions number of FILE in repo.
 > cvs log FILE               

See diff between VER1 and VER2
 > cvs diff -r VER1 -r VER2   

To see your edits in windiff.
 > cvs up -p -r BASE FILE > x; windiff FILE x 


Slash to backslashes,  ie. do $X =~ s,/,\\,g; 
  > echo ${X//\//\\}  

Windiff cannot handle /, needs only \\.
  windiff(){
    echo "windiff.exe ${1//\//\\} ${2//\//\\} &"
          windiff.exe ${1//\//\\} ${2//\//\\} &
  }

Windiff your changes:
  cvs-windiff() {
    if [[ ! -r "$1" || ! -w "/tmp" ]] ; then
        echo "Usage: cvs-windiff FILES, need \\\\tmp to checkout cvs BASE files."
        return
    fi
    for i in $@ ; do
        echo "cvs up -r BASE -p $i > \\\\tmp\\\\$i"
        cvs up -r BASE -p $i > /tmp/$i ;
    done
    windiff.exe . \\tmp &
  }
