+%  *    COMMANDS FOR USE WITH MNRAS.BST    *
+%  ****************************************
+%
+% The following three macros provide auxiliary support for the BibTeX
+% wranglings in mnras.bst.  They provide support for functionality
+% which it is impossible, or at least unmaintainably arcane, to
+% provide within BibTeX Style Language.
+%
+% These definitions can be loaded as a package or, probably better,
+% should be incorporated into a mnras.cls file.
+%
+% These depend on the presence of a \href{URL}{text} macro, as
+% provided by the hyperref package.  The mnras.bst style depends
+% additionally on the \url{URL} macro, which hyperref also provides.
+%
+% If the hyperref package is not included, then suitable defaults are
+%
+%   \def\href#1#2{#2}
+%   \def\@url#1{#1\endgroup}
+%   \def\url{\begingroup\@urlcharsother \ttfamily \@url}
+%
+% These must appear _after_ this package is loaded, and should appear
+% _instead_ of loading the hyperref package (it'll probably be OK to
+% let the hyperref package redefine these, but that is to tempt fate).
+
+
+% \@urlcharsother
+%
+% 'Other' some characters which may appear in DOIs and URIs.
+%
+% All of the characters here may appear in URIs, except for '^' and '\'.
+%
+% There appear to be almost no restrictions on what characters appear
+% in DOIs (or at least none discovereable in ISO 26324:2012, which
+% says simply that the 'DOI suffix' is "a character string of any
+% length".  A DOI registrant which uses characters outside ASCII plus
+% the following set, is a DOI registrant who should be taken outside
+% and challenged on their taste.
+%
+% The following list is not simply \dospecials, because that includes
+% '{' and '}', which we need.  And if they're in a DOI... well.
+\def\@urlcharsother{%
+  \let\do\@makeother 
+  \do\\\do\$\do\&\do\#\do\^\do\_\do\%\do\~}
+
+% \doi
+%
+% \doi{10.foo} formats the DOI in the argument, and provides a link to dx.doi.org.
+% \doi[text]{10.foo} formats the DOI 10.foo, but provides 'text' as the link.
+% The DOI can contain {\$&#^_%~} (though there's not necessarily a
+% guarantee that these will still work as URL characters within the PDF)
+\def\doi{\begingroup
+  \@urlcharsother
+  \@ifnextchar[%
+    {\@doi}
+    {\@doi[]}}
+\def\@doi[#1]#2{%

+  \fi
+  \endgroup
+  }
+
+% \eprint
+%
+% \eprint{defaultArchivePrefix}{id} expands to a link to the given ID
+% at a suitable archive.  The 'id' can be either a bare ID (such as
+% yymm.1234) for arXiv, or can include an archive prefix.  If there is
+% no prefix in the 'id', then 'defaultArchivePrefix' supplies a default.
+%
+% Thus
+%   \eprint{}{arXiv:yymm.1234} -> \href{http://arxiv.org/abs/yymm.1234}{arXiv:yymm.1234}
+%   \eprint{}{yymm.1234} -> same as \eprint{}{arXiv:yymm.1234}
+%   \eprint{arXiv}{arXiv:yymm.1234} -> same
+%   \eprint{dblp}{1234} -> \href{http://dblp.uni-trier.de/rec/bibtex/1234.xml}{dblp:1234}
+%   \eprint{dblp}{arXiv:yymm.1234} -> same as \eprint{}{arXiv:yymm.1234}
+%   \eprint{}{wibble:1234} -> wibble:1234 (doesn't match anything)
+%
+% A prefix 'PFX' is 'registered' by defining a macro
+% \@eprint@PFX#1{...} which formats the identifier (that is, \eprint's
+% second argument _minus_ any colon-terminated prefix).
+\def\eprint#1#2{%
+  \@eprint#1:#2::\@nil}
+\def\@eprint@arXiv#1{\href{http://arxiv.org/abs/#1}{{\tt arXiv:#1}}}
