Command Explanations

cp makefiles/makefile.linux Makefile: There are no autotools shipped with this package. The Linux Makefile is copied to the root of the source tree, facilitating the installation.

sed -i -e 's/unroll-loops/& -fPIC/' Makefile: Add a gcc option to make the build compatible with x86_64 systems.

install ...: The documentation files are not installed by the installation procedure, so they are copied manually.
