-By default, this will install into /usr/local.  If you want to install this
-libdrm to replace your system copy, say:
+libdrm - userspace library for drm
 
-./autogen.sh --enable-system
+This  is libdrm,  a userspace  library for  accessing the  DRM, direct
+rendering  manager, on  Linux,  BSD and  other  operating systes  that
+support the  ioctl interface.  The library  provides wrapper functions
+for the  ioctls to avoid  exposing the kernel interface  directly, and
+for chipsets with drm memory manager, support for tracking relocations
+and  buffers.   libdrm  is  a  low-level library,  typically  used  by
+graphics drivers  such as the Mesa  DRI drivers, the  X drivers, libva
+and  similar projects.  New  functionality in  the kernel  DRM drivers
+typically requires  a new  libdrm, but a  new libdrm will  always work
+with an older kernel.
+
+
+Compiling
+---------
+
+libdrm  is  a  standard  autotools  packages and  follows  the  normal
+configure, build  and install steps.   The first step is  to configure
+the package, which is done by running the configure shell script:
+
+	./configure
+
+By default, libdrm  will install into the /usr/local/  prefix.  If you
+want  to  install   this  DRM  to  replace  your   system  copy,  pass
+--prefix=/usr and  --exec-prefix=/ to configure.  If  you are building
+libdrm  from a  git checkout,  you first  need to  run  the autogen.sh
+script.  You can  pass any options to autogen.sh  that you would other
+wise  pass to configure,  or you  can just  re-run configure  with the
+options you need once autogen.sh finishes.
+
+Next step is to build libdrm:
+
+	make
+
+and once make finishes successfully, install the package using
+
+	make install
+
+If you are install into a system location, you will need to be root to
+perform the install step.
