# Function 'preconfig filename [remove]'
#
#   param1 (required) may be a wildcard;

#   param2 (optional) has value 'remove'

# Description:
# Prepare the incoming configuration files which are not allowed
# to overwrite existing ones.
# These files will get a '.new' extension.
# An entry in the 'doinst.sh' script will be created for these files, copying
# the *.new files back to their original names,
# but only if the original names don't exist.
# Use the second parameter 'remove', like in 'preconfig filename(s) remove'
# to add a 'rm -f filename.new' in 'doinst.sh', so as not to clutter
# the harddisk with useless example files.
