******************************************************************************
ABOUT-FINDLIB - Package manager for O'Caml
******************************************************************************
==============================================================================
Abstract
==============================================================================
The findlib library provides a scheme to manage reusable software components
(packages), and includes tools that support this scheme. Packages are
collections of OCaml modules for which metainformation can be stored. The
packages are kept in the filesystem hierarchy, but with strict directory
structure. The library contains functions to look the directory up that stores
a package, to query metainformation about a package, and to retrieve dependency
information about multiple packages. There is also a tool that allows the user
to enter queries on the command-line. In order to simplify compilation and
linkage, there are new frontends of the various OCaml compilers that can
directly deal with packages.
Together with the packages metainformation is stored. This includes a version
string, the archives the package consists of, and additional linker options.
Packages can also be dependent on other packages. There is a query which finds
out all predecessors of a list of packages and sorts them topologically. The
new compiler frontends do this implicitly.
Metainformation can be conditional, i.e. depend on a set of predicates. This is
mainly used to be able to react on certain properties of the environment, such
as if the bytecode or the native compiler is invoked, if the application is
multi-threaded, and a few more. If the new compiler frontends are used, most
predicates are found out automatically.
There is special support for scripts. A new directive, "#require", loads
packages into scripts. Of course, this works only with newly created toploops
which include the findlib library.
