[+NAME?simplefileattributetree1 - generate compound variable tree which contains file names and their attributes]
[+DESCRIPTION?\bsimplefileattributetree1\b is a simple variable tree
demo which builds a compound variable tree based on the output
of /usr/xpg4/bin/file which contains the file name, the file attributes
and optionally file type and content]
[b:benchmark?Print time needed to generate the tree.]
[c:includecontent?Include the file\'s content in the tree, split into 1kb blocks.]
[t:includefiletype?Include the file type (output of /usr/xpg4/bin/file).]
