.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Lintian::Output is used for all interaction between lintian and the user.
It is designed to be easily extensible via subclassing.
.PP
To simplify usage in the most common cases, many Lintian::Output methods
can be used as class methods and will therefore automatically use the object
\&\f(CW$Lintian::Output::GLOBAL\fR unless their first argument \f(CW\*(C`isa(\*(AqLintian::Output\*(Aq)\*(C'\fR.

Determine how verbose the output should be.  \*(L"0\*(R" is the default value
(tags and msg only), \*(L"\-1\*(R" is quiet (tags only) and \*(L"1\*(R" is verbose
(tags, msg and v_msg).

These methods can be used both with and without an object.  If no object

Like \*(L"v_msg\*(R", except output is possibly sent to a dedicated log
file.

not be prefixed.  Will do nothing unless perf_debug is set to a
