Adds a `webpage' BibTeX entry type, and support for general `url' and
`lastchecked' fields, to arbitrary BibTeX style files.

    %%VERSION%% 0.2

The Perl script urlbst.pl can be used to add this support to an
arbitrary .bst file which has a reasonably `conventional' structure.
The result is meant to be robust rather than pretty.

Usage
-----

    urlbst.pl [input-file [output-file]]

if either the input-file or the output-file is omitted, they default
to stdin and stdout respectively.  If the input file already has a URL
entry type, then the script objects.

The distributed files abbrvurl.bst, alphaurl.bst, plainurl.bst and
unsrturl.bst are versions of the standard style files which have been
pre-converted.

Only the style files which result from conversion of the standard
styles are checked in the regression tests.  Other style files which
are known to work include

    acm.bst, amsalpha.bst, amsplain.bst, apalike.bst, gerabbrv.bst,
    geralpha.bst, gerapali.bst, gerplain.bst, gerunsrt.bst, ieeetr.bst and
    siam.bst

Style files known not to work, because they are too different from the
standard styles, include the koma-script styles and the refer styles
(they are not designed to produce conventional .bbl files).  The
natbib and revtex style files already have URL fields.  If you have a
BibTeX style file which you think ought to work, but with which the
script fails, send it to me, and I'll try to work out what I've missed.

Example
-------

    urlbst.pl `kpsewhich siam.bst` siamurl.bst

Installation and documentation
------------------------------

Essentially no installation is necessary.  Simply install the file
urlbst.pl wherever you wish it to live.

Basic documentation is in the file urlbst.tex:

    latex urlbst
    bibtex urlbst
    latex urlbst
    latex urlbst


Changes in version 0.2
----------------------

The `editor' field is now supported in the webpage entry type.  Basic
documentation added in file urlbst.tex
