Several functions print messages in different formats
(message, error, warning, cat, R output) and with different syntaxes
(concatenating parameters or accepting a single argument, appending
a new line, etc.).
This accessory function provides a common interface for different types:
several arguments are accepted and concatenated with the sep
argument;
the format is defined with the format
argument; a date is optionally
placed before the message.
