[eev] Temporary directory

[rubikitch]

Hi,

I usally use `tmpdir' and `tmpdir-clean' function to work in temporary 
directory.

function tmpdir () {
if [ `pwd` = /tmp/tmpdir00 ]; then
else
  oldpwd=`pwd`
  rm -rf /tmp/tmpdir00
  mkdir /tmp/tmpdir00
  cd /tmp/tmpdir00
fi
}
function tmpdir-clean () {
cd $oldpwd
unset oldpwd
rm -rf /tmp/tmpdir00
}
