+A tool to facilitate the installation of OCaml annotation files (.cmt, .cmti, .spot, .spit).
+Many existing OCaml libraries, applications and the compiler itself do
+not produce or install the annotation files (.annot, .cmt, .cmti,
+.spot, .spit) which are essential for sub-expression type queries
+(caml-types.el), definition seaches and code refactoring (TypeRex and
+OCamlSpotter). If you want to use development tools, you have to:
+* Rebuild all the software from the source, adding -annot/-bin-annot
+ option to compiler flags in build scripts
+ i.e. Makefile/OCamlBuild/OMakefile.
+* Install those annotation files together with the library objects and
+ signatures. (Require modification of the build scripts)
+SpotInstall provides a post-installation workaround, consists of two things:
+* A very small compiler patch which activates -annot and -bin-annot if OCAML_ANNOT environment variable is defined. (You no longder need to add -annot/-bin-annot to the build scripts.)
+* A small tool to install annotation files to the library destination directory. (You no longer need to add annotation file installation to the build scripts.)
+For the first workaround, you need a small patch available from::
+ hg clone -b annot https://bitbucket.org/camlspotter/mutated_ocaml
+or included in this source package, ocaml-annot-<version>.patch.
+For the second one, you can use SpotInstall. This tool.
