 The "libut" directory is an alternative way to use uthash, utarray, utlist, 
 utstring and utvector in your programs. You can copy the libut directory
 entirely into your own source tree, then use CFLAGS to add libut/include
@@ -7,15 +9,13 @@ There are two upshots of this. One is that you can just #include "libut.h"
 instead of uthash.h, utarray.h, etc. So it is a convenient wrapper. 
 
 The other benefit of using the libut is that if you do a "make" in libut/
-it builds libut/src/libut.a, which you can then link into your program 
-using LDFLAGS -Llibut/src -lut. This makes the utvector available.

 This also links in the plumbing that supports having a utvector of utstrings.

 NOTE: because the libut/include contains symlinks, to copy this source into
       another source tree, make sure you deref symlinks to copy their contents.
       One way to do this, is to use the tar -h option:
 
- tar cjhf - libut | (cd $DESTDIR; tar xjf -)
+    tar cjhf - libut | (cd $DESTDIR; tar xjf -)
