+# Bash auto-completion script written for lv2_inspect, lv2_jack_host
+# and lv2_simple_jack_host. Could be adapted to any other program
+# that takes an LV2 plugin URI as parameter.
+
+# Written by Lars Luthman <lars.luthman@gmail.com> on 2009-10-12. 
+# No copyright claimed for this script. Do what you want with it.
+
+# For some reason Bash splits the command line not only at whitespace
+# but also at ':' signs before putting the parts into COMP_WORDS.
+# Since ':' is used in all URIs, which are what we want to complete,
+# we have to put the URI back together before we can complete it
+# and then cut off the parts we prepended from the completions.
+# It probably breaks in some special cases but for most common uses
+# it should work fine.
