.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
MARC::Parser::RAW is a lightweight, fault tolerant parser for \s-1ISO 2709\s0 
encoded \s-1MARC\s0 records. Tags, indicators and subfield codes are not validated 
against the \s-1MARC\s0 standard. Record length from leader and field lengths from 
the directory are ignored. Records with a faulty structure will be skipped 
with a warning. The resulting data structure is optimized for usage with the 
Catmandu data tool kit.
.PP
MARC::Parser::RAW expects \s-1UTF\-8\s0 encoded files as input. Otherwise provide 
a filehande with a specified I/O layer or specify encoding.
.SH "MARC"
.IX Header "MARC"
The \s-1MARC\s0 record is parsed into an \s-1ARRAY\s0 of ARRAYs:
