[postgis-devel] news from the head branch

[strk at refractions.net]

Just to keep you in sync about devs on the HEAD branch:

	- added a LineMerge function (using GEOS)

	- added initial interface for the GEOS C api

A few words about the GEOS-CAPI interface.

The GEOS C api (still poorly tested) provides an abstraction
layer aimed at protecting library binary interface.

This means that if you link postgis against the ligeos_c.so,
you theoretically would not be required to rebuild it when
upgrading GEOS. New GEOS installation would override the
libgeos_c.so file so to attach it to new GEOS library.

If you want to join the exciting segfaults adventure:

	- get GEOS head branch from CVS and install it

	- get PostGIS head branch, configure adding --with-geos-capi
	  and instal it
