Summary description: Draw continuous or discrete spectra using PGF/TikZ
Announcement text: ----------------------------------------------------------------------
The purpose of this package is to draw the spectrum of elements in a simple way. It is based on the package pst-spectra, with similar options, but also adding some extra options.
It relies on PGF/TikZ to draw the desired spectrum, continuous or discrete. As in pst-spectra, there are data available for the spectra of 99 elements and their ions (from the NASA database). It also allows the user to draw a spectrum with their own personal data.
