.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
DPKG::Parse::Entry parses a dpkg \*(L"Package\*(R" file entry, creating a new
DPKG::Parse::Entry instance for it.  You submit the contents, beginning
with a \*(L"Package:\*(R" line, as the 'data' argument to new.  After that, all
the data is populated as lowercased instance methods.  For example, if
we used the above to create an \f(CW$entry\fR object, we would have:
.PP
.Vb 3
\&   $entry\->package == "kernel\-image\-2.6.12.2"
\&   $entry\->size    == 4293154
\&   $entry\->md5sum  == 2acf846b127b71a1fa1143214b2b85a9
.Ve
.PP
DPKG::Parse::Entry will skip any attribute it does not know about.  You
can see what it has skipped by passing a true value to the 'debug' option to
\&'\fInew()\fR'.
.PP
It should know all the attributes present in a Packages, available, and
status file.
.PP
See DPKG::Parse::Status, DPKG::Parse::Available, and
DPKG::Parse::Packages for more information on how to easily generate
DPKG::Parse::Entry objects.
.SH "METHODS"
.IX Header "METHODS"
.IP "Accessor Methods" 4
.IX Item "Accessor Methods"
The following accessor methods correspond directly to the values found in
the parsed Package block, with one exception: \*(L"\-\*(R" characters are replaced
with \*(L"_\*(R".  So, \*(L"build-essential\*(R" becomes \*(L"build_essential\*(R".
.Sp
The accessors are:

.el .IP "new('data' => \f(CW$data\fR, 'debug' => 1)" 4
.IX Item "new('data' => $data, 'debug' => 1)"
Creates a new DPKG::Parse::Entry object.  'data' should be a scalar that
contains the text of a dpkg-style Package entry.  If the 'debug' flag is
set, we will Carp about entries we don't have accessors for.
.ie n .IP "parse('data' => $data);" 4
.el .IP "parse('data' => \f(CW$data\fR);" 4
.IX Item "parse('data' => $data);"
Does the actual parsing of the Package block given to \fInew()\fR.  Probably
should only be called once per object.
