Adding PACKAGE_PATCHLEVEL to an extension

I added these lines to my configure.ac file:

AC_SUBST([PACKAGE_PATCHLEVEL], [1.0.1])
AC_DEFINE_UNQUOTED(PACKAGE_PATCHLEVEL, "$PACKAGE_PATCHLEVEL")

This passes -DPACKAGE_PATCHLEVEL=\"1.0.1\" to the compiler.

My question is, should I call Tcl_PkgProvide("1.0.1") or just
Tcl_PkgProvide("1.0")?
Tcl and Tk pass 8.4 not 8.4.9, while the Tile extension passes 0.6.3 not
0.6.

Also, should my pkgIndex.tcl file call "package provide MyPkg 1.0.1" or
"package provide MyPkg 1.0"? It seems the Tile Windows pkgIndex.tcl file
uses 0.6 while the Tile Unix pkgIndex.tcl file uses 0.6.3.

You should Tcl_PkgProvide("1.0.1") ...

The index script (pkgIndex.tcl file) should not [package provide]
anything at all. It should use [package ifneeded] to trigger a
[load] of the appropriate shared library. During the [load] the
Tcl_PkgProvide() call discussed above will take care of any
[package provide]-ing.

The [package ifneeded] command in your index script should get
the full version number, 1.0.1, as an argument.
