On Mon, 27 Jun 2011 Clemens Niederberger submitted the
chemnum
package.
Summary description: chemnum is a new and hopefully comprehensive approach for the numbering of chemical compounds. It is vaguely inspired by the chemcompounds package.
License type: lppl
Announcement text: ----------------------------------------------------------------------
The package defines a label- and ef-like commands for compound numbers.
Basically two main commands are provided, cmpd{<label name>} and cmpdlist{<comma separated list of label names>}. With them compound labels are initialized, declared and printed. There are some variants of these commands and possibilities to customize them. ----------------------------------------------------------------------
