+- Update README.md, add help when libite is used in autotools projects.
+  Spell checking and minor cleanup.
+
+### Fixes
+- Activate use of `utimensat()` when `pidfile()` is called multiple

+  simply updating the mtime of the PID file.
+- Westermo fixes for `fcopyfile()`: nothing copied on embedded PPC
+  system when using `tmpfile()` as source.
+
+
+[v1.5.0][] - 2016-03-20
+-----------------------
+
+This release changes the header file namespace.  Apologies for any
+problems this may cause!
+
+### Changes
+- Change namespace for header files: `libite/` to `lite/`, e.g. using
+  `pkg-config` your C program must now `#include <lite/lite.h>`
+- Update `pidfile()` to use `utimensat()` to update atime+mtime instead
+  of opening and writing PID again.  Less overhead and nanonsecond res.
+
+
+[v1.4.4][] - 2016-02-23
+-----------------------
+
+### Changes
+- Add `ibite.pc.in` for `pkg-config` support.
+
+### Fixes
+- Fix issue #3: `tempfile()` fails with bad `O_TMPFILE` on some embedded
+  targets, in particular PowerPC.  On systems with older GLIBC but with
+  a sufficiently new kernel `O_TMPFILE` is missing and the local libite
+  definition was wrong, hard coded for x86.  Fixed by Johan Askerin.
+
+
+[v1.4.3][] - 2016-02-02
+-----------------------
+
+### Fixes
+- Remove symlinks to Markdown files from GIT
+- Distribute and install Markdown files: README.md, etc.
+
+
+[v1.4.2][] - 2016-01-23
+-----------------------
+
+### Fixes
+- Fix issue #2: GCC6 `-Wmisleading-indentation` causing FTBFS in pimd,
+  which enables `-Werror`

+
+Library Versioning
+------------------
+
+Libite (-lite) relies on GNU Libtool for building the library.  For a
+user of the library it is important to maintain a clear ABI versioning
+scheme.  This is not the same as the library version, but rather the
+library "compatibility level".
+
+The ABI version is specified in `src/Makefile.am` and looks like this:
+
+    libite_la_LDFLAGS = -version-info 0:0:0
+                                       \ \ `-- age
+                                        \ `--- revision
+                                         `---- current
+
+It must be updated according to the [GNU Libtool recommendations][1]:
+
+1. Start with version information of `0:0:0` for each libtool library.
+2. Update the version information only immediately before a public
+   release of your software.  More frequent updates are unnecessary, and
+   only guarantee that the current interface number gets larger faster.
+3. If the library *source code has changed at all* since the last update,
+   then increment revision (`c:r:a` becomes `c:r+1:a`).
+4. If any *interfaces have been added, removed, or changed* since the
+   last update, increment current, and set revision to 0.
+5. If any *interfaces have been added* since the last public release,
+   then increment age.
+6. If any *interfaces have been removed or changed* since the last
+   public release, then set age to 0.
+
+The libtool ABI versioning logic is very confusing but works if you just
+disable your brain and follow the rules, one by one.
+
+**Example #1:** a new function has been added, none of the existing ones
+have changed.  The initial version is 1:0:0, we follow the rules above to
+the letter: increase revision, increase current and set revision to zero,
+and finally increase age.  This, rather confusingly, gives us 2:0:1 which
+libtool then translates to `libconfuse.so.1.1.0`.
+
+**Example #2:** some existing functions are changed, they now return an
+`int` instead of `void`.  The initial version is 0:0:0, and we follow the
+rules again: increment revision, increment current and set revision to
+zero, set age to zero.  This gives us 1:0:0, which is then translated to
+ `libconfuse.so.1.0.0`.
+
+### Note
+
+Usually, non-developers have no interest in running development versions
+(releases are frequent enough), and developers are expected to know how
+to juggle versions.  In such an ideal world, it is good enough to bump
+the library version just prior to a release, point 2.
+
+However, if releases are few and far between, distributors may start to
+use snapshots.  When a distributor uses a snapshot, the distributor has
+to handle the library version manually.  Things can get ugly when the
+distributor has released an intermediate version with a bumped library
+version, and when the official release is bumped to that version, the
+distributor will then have to bump the library version for the official
+release, and it can be confusing if someone reports bugs on versions
+that you didn't even know existed.
+
+The problem with bumping the version with every change is that if your
+interface is not finished, the version number might run away, and it
+looks pretty bad if a library is at version 262.  It kind of tells the
+user that the library interface is volatile, which is not good for
+business.

+Introduction
+------------
+
+Libite is a lightweight library of *frog DNA* that can be used to fill
 the gaps in any dinosaur project.  It holds useful functions and macros
 developed by both [Finit][1] and the [OpenBSD][2] project.  Most notably
 the string functions: [strlcpy(3)][3], [strlcat(3)][3] and the highly
 useful *BSD [sys/queue.h][4] and [sys/tree.h][7] API's.
 
-Libite aims to fill in the gaps missing in GLIBC/EGLIBC.  (It does not

-are extremely liberal and can be used freely in proprietary software if

-For an introduction to why Libite happened, and how you can use it, see
+
-[this blog post][6].
+Using -lite
+-----------
+
+Libite is by default installed as a library and a set of include files.
+To prevent clashing with include files of the same name `-lite` employs
+an include file namespace `lite/`, which is strongly recommended to use
+in your applications:
+
+    #include <lite/lite.h>
+    #include <lite/conio.h>
+    #include <lite/queue.h>
+    #include <lite/tree.h>
+
+The output from the `pkg-config` tool holds no surprises in this regard:
+
+    $ pkg-config --libs --static --cflags libite
+    -I/usr/local/include -L/usr/local/lib -lite
+
+The prefix path `/usr/local/` shown here is only the default.  Use the
+`configure` script to select a different prefix when installing libite.
+
+For GNU autotools based projects, use the following in `configure.ac`:
+
+    # Check for required libraries
+    PKG_CHECK_MODULES([lite], [libite >= 1.5.0])
+
+and in your `Makefile.am`:
+
+    proggy_CFLAGS = $(lite_CFLAGS)
+    proggy_LDADD  = $(lite_LIBS)
+
+
+Important Note
+--------------
+
+When using functions like `mkpath()`, `makepath()`, and `makefifo()`,
+make sure your `umask()` is correct so you do not accidentally create
+files and directories accessible to other users than intended.

+ Libite is a lightweight library of frog DNA.  It can be used to fill
+ the gaps in any dinosaur project.  It holds useful functions and macros

+#> connections which carry long term conversations.  For the purpose of
