\begin{abstract}\noindent
\LaTeX\ internally inserts `\@finalstrut<strutbox>'
at the end of footnotes or `p' (paragraph) `tabular' cells.
When the user's entry ends on a `\par' token---which may 
be issued by some more-general-purpose user macro 
such as the `\lipsum' command from the \ctanpkgref{lipsum}
package\urlfoot{CtanPkgRef}{lipsum} for dummy text---this 
produces a usually unwanted extra, empty line.
'finstrut.sty' changes `\@finalstrut' in order to avoid 
this effect.
  \par
The first version of the package just had this minimum purpose. 
But then Donald Arseneau has convinced me to consider 
a wide range of cases and to replace my code by his proposals.
v0.5 again adds an idea of my own ones:     %% 2011/03/14:
instead of testing for `hmode' vs.~`vmode', 
`vmode' may be \emph{forced} by a `\par'---saves tokens!
In order not to break code that some package writers may have 
used so far, choices by package options are offered.
v0.4 offered choice among 6 definitions, with v0.5 they are 9---!
(Not 9!.)

\section{Remark on 'lipsum'}
Almost at the same moment that 'finstrut' v0.1 was installed 
(2011-02-09), a new version v1.1    %% v0.4: v1.1
of 'lipsum' was uploaded that offers a package option 
`[nopar]'                           %% v0.4
to avoid a final `\par'.

\section{Installing and Calling}
The package file 'finstrut.sty' is provided ready, 
installation only requires putting it somewhere where \TeX\ finds it 
(which may need updating the filename data 
 base).\urlfoot{ukfaqref}{inst-wlcf}

Below the `\documentclass' line(s) and above `\begin{document}', 
you load 'finstrut.sty' (as usually) by 
\[`\usepackage{finstrut}'\qquad \mbox{or by}\qquad 
  `\usepackage[<options>]{finstrut}'\]---<options> described below.
