"""
"refextract" is used to extract and process the "references"
or "citations" made to other documents from within a document.
A document's "references" section is usually found at the end of
the document, and generally consists of a list of the works
cited during the course of the document.
"refextract" can attempt to identify a document's references
section and extract it from the document. It can also attempt
to standardise the references (correct the names of journals
etc so that they are written in a standard format), and mark them
up so that they can be linked to the full articles on the Web by
means of hyper-links.
"refextract" has 4 phases of processing (passes):
1. Convert PDF file to plaintext (UTF-8).
2. Extract References from plaintext.
3. Recognise and standardise citations in the extracted
reference lines. (Periodical titles and institutional
report numbers are standardised with the aid of
dedicated knowledge-bases.)
4. Markup standardised citations in MARC XML and output
them.
It requires providing as argument a physical fulltext file using
[-f, --fulltext].
