+%
+% |\begin{tabulary}|^^A
+% \marg{length}\marg{pream}| |\ \ldots\ |\end{tabulary}|
+%
+% The rather daft name may change in a later release but it is a pun
+% on |tabularx|, which itself was a pun on |tabular*|\ldots
+%
+% These environments work pretty much like the standard tabular
+% environment (or more correctly, the enhanced version from the array
+% package) except that there are more possibilities for the column
+% types.
+% \begin{description}
+% \iffalse
+% \item[s] An `|s|' column relates to a `|c|' column the way the |[s]|
+% |\makebox| option relates to |[c]|. The entries are set to the
+% widest width in the column, but no centering is done, any `glue' in
+% the entry will be used to `stretch' the text across the column. This
+% package adds the |s| column type to \emph{all} array and tabular
+% environments.
+% \fi
+% \item[LCRJ] These new `uppercase' column types are only activated in
+% the |tabulary| environment.
+% In order to make the total table width equal to \meta{length} the
+% |LCRJ| columns are converted to |p| columns (with |\raggedright|,
+% |\centering|, or |\raggedleft| or normal justification respectively
+% applied). The width of these converted columns is proportional to
+% the natural width of the longest entry in each column.
+% \end{description}
+%
+% To stop very narrow columns being too `squeezed' by this process any
+% columns that are narrower than |\tymin| are set to their natural
+% width. This length may be set with |\setlength| and is
+% arbitrarily initialised to 10\,pt. (If you know that a column will
+% be narrow, it may be preferable to use, say, |c| rather than |C| so
+% that the \textsf{tabulary} mechanism is never invoked on that column.)
+%
+% Similarly one very large entry can force its column to be too wide.
+% So to prevent this, all columns with natural length greater than
+% |\tymax| are set to the same width (with the proportion being taken
+% as if the natuaral length was \emph{equal} to |\tymax|). This is
+% initially set to twice the text width..
+%
+% Narrow |p| columns are sometimes quite hard to set, and so
+% you may redefine the command |\tyformat| to be any declarations
+% to make just after the |\centering| or |\ragged|\ldots\ declaration.
+% By default it redefines |\everypar| to insert a zero space at the
+% start of every paragraph, so the first word may be hyphenated. (See
+% DogBook).
+%
+%
+% As the environment makes a standard \LaTeX\ box, it will be indented
+% by the paragraph indent at the start of a paragraph, and so will not
+% fit on a line if given argument |\textwidth| unless it is preceded by
+% |\noindent| or is in a |center| environment or some other
+% environment with zero paragraph indent.
+%
+% \section{Features}
+%
+%
+% You can use |\multicolumn| but if the multicolumn text turns out to
+% be longer than the final calculated widths of the columns that it
+% spans, then the final table will be too wide.
+%
+% |\verb| doesnt work. (except in restricted version as in tabularx)
+%
+% The whole table is evaluated twice, so take care with some
+% \TeX\ constructions that may have side effects like writing to files.
+%
+%
+% \section{Options}
+% The following package option is defined:
+% \begin{description}
+% \item[debugshow] Causes a lot of stuff to appear on the terminal.
+% I find this invaluable, you may find it less so.

+%
+% The following examples attempt to show the effect of the |\tymin| and
+% |\tymax| parameters. One should also perhaps note that |\tymax|
+% refers to the total column width (inluding any inter-column space,
+% rules etc) but |\tymin| just refers to the width of the column entry
+% (like the argument to the standard |p| column).
+%
+% \test{0pt}{\maxdimen}{Note how the first column is `squeezed'.
+% In fact it is in such a narrow column that even `a' produces an
+% overfull box warning!}
+%
+% \test{20pt}{\maxdimen}{Here increase \texttt{\string\tymin} so that
+% columns b and a are not so narrow. `a' is set to its natural width,
+% and `b' is set to \texttt{\string\tymin}.}
+%
+% \test{20pt}{200pt}{In the previous example, the large d column
+% dominated the table, being a lot wider than the c column. By
+% reducing \texttt{\string\tymax} can limit the width of column d
+% producing more even column widths, but now producing an entry for d
+% that is longer than that for c.}
