url: the url to download the file.
package_file: the filename of the downloaded url. If not
specified, taken to be basename(url). This should rarely
need to be specified.
specified on the commandline to just benchmark a single project.
name: the name used to identify the project when listing projects
on the benchmark commandline. If not specified, taken to be
package_file, but with the .tar.* extension removed.
md5: the output of 'md5sum package_file'; used to verify a download.
unpacked_subdir: The top-level directory created when we untar the
package_file. If not specified, taken to be self.name, which is
typically right (at least for projects make using autotools).
build_subdir: the subdirectory of unpacked_subdir where building
should be done; we create it if needed. Defaults to '.'.
You should only need to change this if your project does not
have its configure script in the top-level directory.
configure_cmd: the command to generate the project's Makefile.
It is run in build_subdir. Defaults to './configure'.
pre_build_cmd: a command to run before running the build command.
It is run in build_subdir. Defaults to running nothing.
build_cmd: The command to build the project from the Makefile.
We add VAR=val arguments, so build_cmd must be a single command
that is either a form of 'make', or takes the same style
arguments. Defaults to 'make'.
include_server_args: include server tweaks such as stat reset triggers
for builds that modify source files.
