IO::Lines \- IO:: interface for reading/writing an array of lines

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class implements objects which behave just like FileHandle
(or IO::Handle) objects, except that you may use them to write to
(or read from) an array of lines.  \f(CW\*(C`tiehandle\*(C'\fR capable as well.
.PP
This is a subclass of IO::ScalarArray
in which the underlying
array has its data stored in a line-oriented-format: that is,
every element ends in a \f(CW"\en"\fR, with the possible exception of the
final element.  This makes \f(CW\*(C`getline()\*(C'\fR \fImuch\fR more efficient;
if you plan to do line-oriented reading/printing, you want this class.
.PP
The \f(CW\*(C`print()\*(C'\fR method will enforce this rule, so you can print
arbitrary data to the line-array: it will break the data at
newlines appropriately.
.PP
See IO::ScalarArray for full usage and warnings.
