One question that crops up from time to time is ‘How do I install
achemso?’ For most people, I tend to point out that the latest MiKTeX and TeX Live distributions include both
achemso and everything it needs to work. So on a stand-alone system, installing an up-to-date distribution is the easiest way.
achemso itself is not too hard, the main problem being that people miss out the BibTeX files (
biochem.bst), then get odd effects with bibliographies. On CTAN, the file
achemso.tds.zip contains everything laid out ready for installation, and that includes the BibTeX files. So my advice for those who can’t or don’t want to do a full update is to use the TDS
.zip. For those who want to extract from the source and do everything themselves, as I say the main thing is not to forget the BibTeX styles.
One problem that comes up is the need for a reasonably recent copy of
xkeyval. If I was writing the code again from scratch, I probably would not use xkeyval, but that is not the situation. I’ve worked quite hard to reduce the problems, and the latest version of
achemso uses only the most basic functions in
xkyeval. One of the reasons that life is a bit complex is because
xkeyval requires installation of items in both
tex/latex/xkeyval: not ideal. At the moment, there is no TDS
.zip on CTAN for
xkeyval, but I’m always happy to send anyone who needs one a suitable
.zip by e-mail.
