** Additional files
To build the auxiliary tool wsp, you will need an additional file,
wordsplit-version.h. Normally, it should contain only a definition
of the macro or variable WORDSPLIT_VERSION. The following shell
fragment can be used to create it:
To build the auxiliary tool wsp, it is recommended to define the
WORDSPLIT_VERSION macro to the actual version of the wordsplit
package. There are two ways of doing so. First, you can define
WORDSPLIT_VERSION in your config.h or pass its definition via the
AM_CPPFLAGS variable. Secondly, you can create an additional file,
wordsplit-version.h, containing its definition and define the
HAVE_WORDSPLIT_VERSION_H macro to make sure it is included. The
following shell fragment can be used to create the header:
version=$(cd wordsplit; git describe)
cat > wordsplit-version.h <<EOF
