+# we take care of doing variable assignment using the '?=' and '+='
+# operators to preserve the value of variables if they are already
+# defined. In FreeBSD this happens when fasta3 is build from the port or
+# when the user has set these variables -- most notably CC and/or CFLAGS
+# -- in /etc/make.conf
+
+# Compiler executable, and optional flags
+CC?= gcc
+CFLAGS?= -g -O2

+# FreeBSD-6. If you're building fasta3 on your own, you will need to
+# adjust this accordingly. The default works in FreeBSD-6x (currently
+# the recommended major version for use in production). Or better yet,
+# use the biology/fasta3 port from the ports collection, which will use
+# the correct threading library for your OSVERSION
