[texhax] include a pdf graphics file whose name includes a varying date

[Mike Marchywka]

fwiw, as a point of discussion ( I still do not know what all tex has for scripting )
assuming hotmail does not mangle it, here is a script that generates a date in a standard
format and is then modified using tools that work with anything ( 'dohs users can get cygwin ).
Any generated literal can now be shared as a string without having to worry if different apps make
different names sometimes due to various quirks in defaults or other issues.
Once you have a code generator for tex, making code snippets for R or whatever is quite
easy. The code generator script can run and test the apps too ( I use an example I found on stack
exchange to validate bibtex entries). 

$cat testscript 

testdate()
{
cat - << ----
\documentclass{article}
\begin{document}
\begin{verbatim}
$1
\end{verbatim}
\end{document}
----

}

testdate `date  -R | sed -e 's/ /_/g'`


$ ./testscript  > xxx.tex
$ pdflatex xxx.tex

The documentation doesn't have such an option, but shows an example
which uses exaclty Davids code:

\thedateyear/%
\ifnum\value{datemonth}<10 0\fi
\thedatemonth/%
\ifnum\value{dateday}<10 0\fi
\thedateday%

But I don't quite see why one need a package for this.

\the\year-\ifnum\month<10 0\fi\the\month-\ifnum\day<10 0\fi\the\day

works fine.
