Writes a message to the build log or a specified file.
The message can be specified using the message
attribute or as inline content. If neither is included - or the message contains only whitespace - then an empty message will be emitted in the output.
Macros in the message will be expanded.
When writing to a file, the level
attribute is ignored.
Note: Since NAnt 0.86, a newline will no longer be implictly added when writing a message to a file.
