-# SYNOPSIS
-#
-#   AX_EXTEND_SRCDIR
-#
-# DESCRIPTION
-#
-#   The AX_EXTEND_SRCDIR macro extends $srcdir by one path component.
-#
-#   As an example, when working in /home/michael/i3-4.12/build and calling
-#   ../configure, your $srcdir is "..". After calling AX_EXTEND_SRCDIR,
-#   $srcdir will be set to "../../i3-4.12".
-#
-#   The result of extending $srcdir is that filenames (e.g. in the output of
-#   the "backtrace" gdb command) will include one more path component of the
-#   absolute source path. The additional path component makes it easy for
-#   users to recognize which files belong to the PACKAGE, and -- provided a
-#   dist tarball was unpacked -- which version of PACKAGE was used.
-#
-#   As an example, in "backtrace", you will see:
-#
-#     #0  main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187
-#
-#   instead of:
-#
-#     #0  main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187
-#
-#   In case your code uses the __FILE__ preprocessor directive to refer to
-#   the filename of the current source file (e.g. in debug messages), using
-#   the extended path might be undesirable. For this purpose,
-#   AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS,
-#   which can be added to AM_CPPFLAGS in Makefile.am in order to define the
-#   preprocessor directive STRIPPED__FILE__. As an example, when compiling
-#   the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to
-#   "main.c".
-#
-#   There are some caveats: When $srcdir is "." (i.e. when ./configure was
-#   called instead of ../configure in a separate build directory),
-#   AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will
-#   not be achieved because of the way automake specifies file paths:
-#   automake defines COMPILE to use "`test -f '$source' || echo
-#   '\$(srcdir)/'`$source" in order to prefer files in the current directory
-#   over specifying $srcdir explicitly.
-#
-#   The AX_EXTEND_SRCDIR author is not aware of any way to influence this
-#   automake behavior. Patches very welcome.
-#
-#   To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by adding
-#   the following code to configure.ac:
-#
-#     AX_ENABLE_BUILDDIR
-#     dnl ...
-#     AX_EXTEND_SRCDIR
-#
-#   Then also add this bit to Makefile.am (if you wish to use
-#   STRIPPED__FILE__ in your code):
-#
-#     AM_CPPFLAGS = @AX_EXTEND_SRCDIR_CPPFLAGS@
