+Funtools is a "minimal buy-in" FITS library and utility package
+originally developed at the the High Energy Astrophysics Division of
+SAO. Although no longer actively supported at SAO, it is still widely
+used within the astronomical community, especially among X-ray astronomers.
+
+The Funtools library provides simplified access to a wide array
+of file types: standard astronomical FITS images and binary tables,
+raw arrays and binary event lists, and even tables of ASCII column
+data. A sophisticated region filtering library (compatible with ds9)
+filters images and tables using Boolean operations between geometric
+shapes, support world coordinates, etc. Funtools also supports
+advanced capabilities such as optimized data searching using index files.
+
+Because Funtools consists of a library and a set of user programs, it
+is most appropriately built from source. Funtools has been ported to
+Solaris, Linux, Mac OSX (Darwin) and Windows 98/NT/2000/XP. Once the
+source code tar file is retrieved, Funtools can be built and installed
+easily using standard commands:
+
+  ./mkconfigure				# generate all configure scripts
+  ./configure --prefix=[installdir] 	# configuration
+  make					# build the software
+  make install				# install in [installdir]
+
+See the INSTALL instructions (which are based on standard instructions
+for building software using GNU configure) for more information about
+building Funtools.
