# hh-recent-pipemenu - Openbox "Recent Files" pipe menu (GTK-free)
#
# Loosely modeled on CrunchBang++'s cbpp-recent-files-pipemenu
# (github.com/CBPP/cbpp-pipemenus), but that one parses GTK's
# ~/.local/share/recently-used.xbel, which nothing on Hammerhead writes
# (no GTK). Instead: find(1) over $HOME for recently-modified
# docs/images, opened with the matching viewer.
#
# Usage: <menu id="recent-menu" label="Recent Files" execute="hh-recent-pipemenu"/>
