Selador /

Full commit
# This is a new version of the Selador installation script
# It should work more comfortable and on any unix-like system

# You can set the two variables on your own
# By default they take the arguments given

# Your username, i.e. the user working with selador (default is the argument given)

# The group the webserver belongs to (default is the argument given)

# Nothing need to be edited beyond this line (hopefully)

# The Introtext, nothing special...
