+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+This module converts CPAN Meta structures from one form to another.  The
+primary use is to convert older structures to the most modern version of
+the specification, but other transformations may be implemented in the
+future as needed.  (E.g. stripping all custom fields or stripping all
+optional fields.)
+.SH METHODS
+.IX Header "METHODS"
+.SS new
+.IX Subsection "new"
+.Vb 1
+\&  my $cmc = CPAN::Meta::Converter\->new( $struct );
+.Ve
+.PP
+The constructor should be passed a valid metadata structure but invalid
+structures are accepted.  If no meta-spec version is provided, version 1.0 will
+be assumed.
+.PP
+Optionally, you can provide a \f(CW\*(C`default_version\*(C'\fR argument after \f(CW$struct\fR:
+.PP
+.Vb 1
+\&  my $cmc = CPAN::Meta::Converter\->new( $struct, default_version => "1.4" );
+.Ve
+.PP
+This is only needed when converting a metadata fragment that does not include a
+\&\f(CW\*(C`meta\-spec\*(C'\fR field.
+.SS convert
+.IX Subsection "convert"
+.Vb 1
+\&  my $new_struct = $cmc\->convert( version => "2" );
+.Ve
+.PP
+Returns a new hash reference with the metadata converted to a different form.
+\&\f(CW\*(C`convert\*(C'\fR will die if any conversion/standardization still results in an
+invalid structure.
+.PP
+Valid parameters include:
+.IP \(bu 4
+\&\f(CW\*(C`version\*(C'\fR \-\- Indicates the desired specification version (e.g. "1.0", "1.1" ... "1.4", "2").
+Defaults to the latest version of the CPAN Meta Spec.
+.PP
+Conversion proceeds through each version in turn.  For example, a version 1.2
+structure might be converted to 1.3 then 1.4 then finally to version 2. The
+conversion process attempts to clean-up simple errors and standardize data.
+For example, if \f(CW\*(C`author\*(C'\fR is given as a scalar, it will converted to an array
+reference containing the item. (Converting a structure to its own version will
+also clean-up and standardize.)
+.PP
+When data are cleaned and standardized, missing or invalid fields will be
+replaced with sensible defaults when possible.  This may be lossy or imprecise.
+For example, some badly structured META.yml files on CPAN have prerequisite
+modules listed as both keys and values:
+.PP
+.Vb 1
+\&  requires => { \*(AqFoo::Bar\*(Aq => \*(AqBam::Baz\*(Aq }
+.Ve
+.PP
+These would be split and each converted to a prerequisite with a minimum
+version of zero.
+.PP
+When some mandatory fields are missing or invalid, the conversion will attempt
+to provide a sensible default or will fill them with a value of 'unknown'.  For
+example a missing or unrecognized \f(CW\*(C`license\*(C'\fR field will result in a \f(CW\*(C`license\*(C'\fR
+field of 'unknown'.  Fields that may get an 'unknown' include:
+.IP \(bu 4
+abstract
+.IP \(bu 4
+author
+.IP \(bu 4
+license
+.SS upgrade_fragment
+.IX Subsection "upgrade_fragment"
+.Vb 1
+\&  my $new_struct = $cmc\->upgrade_fragment;
+.Ve
+.PP
+Returns a new hash reference with the metadata converted to the latest version
+of the CPAN Meta Spec.  No validation is done on the result \-\- you must
+validate after merging fragments into a complete metadata document.
+.PP
+Available since version 2.141170.
