It would be useful to have a kind of text field option as input parameter in job's configuration.

This would allow one to specify a small text that could be parsed to build executors (shell, maven, ant, etc.) at build time.

Such field would export it's values like:
TEXTFIELD1='some
text
here to be used in build.'
With carriage returns/line feeds, depending on hudson's build platform (Windows or UNIX).

Thanks in advance.
