-
-  Installs ngx_pagespeed and its dependencies.  Can optionally build and install

-
-Options:
-  -v, --ngx-pagespeed-version <ngx_pagespeed version>
-      What version of ngx_pagespeed to build.  Valid options include:
-      * latest-beta
-      * latest-stable
-      * a version number, such as 1.11.33.4
-
-      If you don't specify a version, defaults to latest-stable.
-
-  -n, --nginx-version <nginx version>
-      What version of nginx to build.  If not set, this script only prepares the
-      ngx_pagespeed module, and expects you to handle including it when you
-      build nginx.
-
-      If you pass in 'latest' then this script scrapes the nginx download page
-      and attempts to determine the latest version automatically.
-
-  -m, --dynamic-module
-      Build ngx_pagespeed as a dynamic module.
-
-  -b, --builddir <directory>
-      Where to build.  Defaults to \$HOME.

-      install them.  If you have installed dependencies from source or are on a
-      non-deb non-rpm system, this won't work.  In that case, install the
