This is a small Perl script which will (hopefully) transform your chromium or google-chrome bookmarks file (usually located in your browser's profile directory in ~/.config/) into an Openbox pipe menu.
This script depends on the Perl module JSON::Tiny which can be downloaded with CPAN by executing perl -MCPAN -e 'install JSON::Tiny' in a terminal.
For more information about using pipe menus in Openbox/LXDE check out the wiki documentation for pipe menus.
