  We present Perl Algorithm to Compute continuum and Equivalent Widths (pacce).
We describe the methods used in the computations and the requirements for its
usage. We compare the measurements made with pacce and "manual" ones made using
iraf splot task. These tests show that for SSP models the equivalent widths
strengths are very similar (differences <0.2A) for both measurements. In real
stellar spectra, the correlation between both values is still very good, but
with differences of up to 0.5A. pacce is also able to determine mean continuum
and continuum at line center values, which are helpful in stellar population
studies. In addition, it is also able to compute the uncertainties in the
equivalent widths using photon statistics. The code is made available for the
community through the web at http://www.if.ufrgs.br/~riffel/software.html.
