This is pgf-spectra, version 1.0 (15/04/2016).

This package provides the \pgfspectra[<options>] command which draws continuous and emission or absorption spectra for 99 elements and their ions.
It was developed mainly for the writing of my own documentation and exams sheets supporting directly PDF output format.
The drawing is made with the TikZ package and is based in the pst-spectra extension for PSTricks.

** Requirements
TikZ and ifthen packages.

** Installation
Unpack everything in a directory in the TeX search path and refresh the TeX database.
