# install mysqld, the python wrappers for mysql and libxml2, start mysqld
# Change the root passwd of mysql:
# mysqladmin -u root password new_password
# Create the new database xmlsoft
# mysqladmin -p create xmlsoft

# change veillard and abcde with the right user name and passwd

# mysql -p xmlsoft
# Enter password:
# Welcome to the MySQL monitor....
# mysql> use xmlsoft
# Database changed
# mysql> quit

# Then run the script in the doc subdir, it will create the symbols and

# by nobody@loaclhost the user expected to be Apache's one
