+which can identify and fit hundreds of lines in emission line spectra in just a
+few seconds with following features:
+@itemize
+
+@item A population of synthetic spectra is generated using a reference line
+catalogue.
+
+@item The goodness of fit for each synthetic spectrum is calculated. The best
+sets of parameters are retained and the rest discarded.
+
+@item A new population of synthetic spectra is obtained by averaging pairs of
+the best performers.
+
+@item A small fraction of the parameters of the lines in the new generation are
+randomly altered.
+
+@item The process repeats until a good fit is obtained.
