+ <i>Barcodes Nomenclatures</i> define how barcodes are recognized and categorized.
+ When a barcode is scanned it is associated to the <i>first</i> rule with a matching
+ pattern. The pattern syntax is that of regular expression, and a barcode is matched
+ if the regular expression matches a prefix of the barcode.
+ </p><p>
+ Patterns can also define how numerical values, such as weight or price, can be
+ encoded into the barcode. They are indicated by a <code>{NNN}</code> where the N's
+ define where the number's digits are encoded. Floats are also supported with the
+ decimals indicated with D's, such as <code>{NNNDD}</code>. In these cases,
+ the barcodes on the associated entites <i>must</i> have the value part set to
+ zeroes.
