Make startup faster by reducing the frequency of garbage collection.

To support org-babel, check if it can find the symlink to ob-beancount.el

#+BEGIN_SRC shell :tangle no
orgpath=`find /home/marc/.emacs.d/elpa/ -type d -name "org-plus*" -print`
beansym="$orgpath/ob-beancount.el
  bean="/home/marc/Archiv/Programmierprojekte/Lisp/beancount-mode/ob-beancount.el"

  if [ -h "$beansym" ]
  then
    echo "$beansym found"
  elif [ -e "$bean" ]
  then
    echo "creating symlink"
    ln -s "$bean" "$beansym"
  else
    echo "$bean not found, symlink creation aborted"

Fava is strongly recommended.

#+BEGIN_SRC shell  :tangle no
cd /opt
python3 -m venv fava
source ./fava/bin/activate
pip3 install wheel
pip3 install fava
deactivate
#+END_SRC

Start fava with fava my_file.beancount

It is accessable on this URL: [[http://127.0.0.1:5000][Fava]]
Beancount-mode can start fava and open the URL right away. 

* Stuff after everything else
Set garbage collector to a smaller value to let it kick in faster.
Maybe a problem on Windows?
