 The Perl script pulls in both `preamble.tex` and `postamble.tex.` The preamble contains all the configuration and style declarations. Note that the LaTeX file `sicp.tex` will be generated on the fly, overwriting the previous version.

This is fine, because all non-Texinfo content remains unchanged by the script.

Newer TeX Live or fonts could result in different character metrics, so that some figures no longer fit. The problem is reported in issue [#5](https://github.com/sarabander/sicp-pdf/issues/5).
