.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module creates constants used by other modules in order to
determine what debugging output should be generated.
.PP
The interface is currently experimental.
.SH "USAGE"
.IX Header "USAGE"
Currently, the only way to turn on debugging is by setting the
\&\f(CW\*(C`ALZABO_DEBUG\*(C'\fR environment variable.  This variable can contain
various flags, each separated by a pipe char (|).  Each flag turns on
different types of debugging output.
.PP
These flags \fBmust be set before Alzabo is loaded\fR, as debugging is
turned on or off through the use of constants.
.PP
The current flags are:
.IP "\(bu" 4
\&\s-1SQL\s0
.Sp
Generated \s-1SQL\s0 and its associated bound variables.
.IP "\(bu" 4
\&\s-1TRACE\s0
.Sp
A stack trace will be generated any time \s-1SQL\s0 is generated.
.IP "\(bu" 4
\&\s-1METHODMAKER\s0
.Sp
The \f(CW\*(C`Alzabo::MethodMaker\*(C'\fR module will generate verbose output
describing the methods it is creating.
.IP "\(bu" 4
\&\s-1REVERSE_ENGINEER\s0
.Sp
The modules involved in reverse-engineering will generate output
describing what it finds during reverse-engineering.
.IP "\(bu" 4
\&\s-1ALL\s0
.Sp
Turn on all flags.
.PP
For now, all debugging output is sent to \f(CW\*(C`STDERR\*(C'\fR.
