libraries, and is mainly intended for internal use.

.IX Header "FUNCTIONS"
.ie n .SS "cp_msg(""message string"" [,VERBOSE])"
.el .SS "cp_msg(``message string'' [,VERBOSE])"
.IX Subsection "cp_msg(message string [,VERBOSE])"
Records a message on the stack, and prints it to \f(CW\*(C`STDOUT\*(C'\fR (or actually
\&\f(CW$MSG_FH\fR, see the \f(CW\*(C`GLOBAL VARIABLES\*(C'\fR section below), if the
\&\f(CW\*(C`VERBOSE\*(C'\fR option is true.
The \f(CW\*(C`VERBOSE\*(C'\fR option defaults to false.
.SS "\fImsg()\fP"
.IX Subsection "msg()"
An alias for \f(CW\*(C`cp_msg\*(C'\fR.
.ie n .SS "cp_error(""error string"" [,VERBOSE])"
.el .SS "cp_error(``error string'' [,VERBOSE])"
.IX Subsection "cp_error(error string [,VERBOSE])"
Records an error on the stack, and prints it to \f(CW\*(C`STDERR\*(C'\fR (or actually

.SH "CLASS METHODS"
.IX Header "CLASS METHODS"
.SS "CPANPLUS::Error\->\fIstack()\fP"
.IX Subsection "CPANPLUS::Error->stack()"
Retrieves all the items on the stack. Since \f(CW\*(C`CPANPLUS::Error\*(C'\fR is
implemented using \f(CW\*(C`Log::Message\*(C'\fR, consult its manpage for the
function \f(CW\*(C`retrieve\*(C'\fR to see what is returned and how to use the items.
.SS "CPANPLUS::Error\->stack_as_string([\s-1TRACE\s0])"
.IX Subsection "CPANPLUS::Error->stack_as_string([TRACE])"
Returns the whole stack as a printable string. If the \f(CW\*(C`TRACE\*(C'\fR option is
true all items are returned with \f(CW\*(C`Carp::longmess\*(C'\fR output, rather than
just the message.
\&\f(CW\*(C`TRACE\*(C'\fR defaults to false.
.SS "CPANPLUS::Error\->\fIflush()\fP"
.IX Subsection "CPANPLUS::Error->flush()"
Removes all the items from the stack and returns them. Since
\&\f(CW\*(C`CPANPLUS::Error\*(C'\fR is  implemented using \f(CW\*(C`Log::Message\*(C'\fR, consult its
manpage for the function \f(CW\*(C`retrieve\*(C'\fR to see what is returned and how
to use the items.
.SH "GLOBAL VARIABLES"

.IX Item "$ERROR_FH"
This is the filehandle all the messages sent to \f(CW\*(C`error()\*(C'\fR are being
printed. This defaults to \f(CW*STDERR\fR.
