+# MacOS build script for NGSPICE
+
+# Considering a MacOS 10.12 system, there are some prerequisites to be satisfied:
+# 1) Install an X11 system of your choice. XQuartz from SourceForge is fine: https://www.xquartz.org
+# 2) Install automake, autoconf, libtool and an updated version of bison by using the method you prefer.
+#    From sources, from 'brew' or from 'MacPorts' are the known ones and I prefer using MacPorts,
+#    available at this address: https://www.macports.org .
+#    You can install from a tarball or you can use the installer, which will also configure the PATH.
+#
+# Said that, the script is quite linear and simple.
