2		Green Hills Software Low-level Library Source
3
4These source files contain low level routines that can be
5modified and/or customized for the user's target environment.

7The Green Hills Development Guide contains a chapter describing
8in more detail the runtime environment and library system implemented
9by these modules.
10
11These source files comprise one binary files which is typically
12included in the architecture-specific library directories which are
13part of a cross-distribution package: libsys.a.
14
15libsys.a is the low-level system call library. This library includes
16such routines as open(), write(), and exit() which together provide a
17full-featured runtime environment.  The library also contains
18routines that control runtime profiling, a feature of the MULTI
19Development Environment.  A small amount of architecture-specific
20assembly code used to accomplish various low-level tasks is included in the
21library as well.
22
23To rebuild libsys.a using the included project file, libsys.bld,
24select the libsys.bld field from within the parent project and use the
25"Build Selected Files" option of the MULTI Builder's "Build" menu.
