+Routines to handle .inf files.
+
+This library is used to share .inf handling code between build tools and
+ReactOS code. Two versions are built, "inflib_host" (for use by build tools)
+and "inflib" (for use by ReactOS code). Both depend on the same core source,
+with a wrapper for the appropriate interface.
+Most of the differences between the host and the ReactOS environment are
+abstracted away in builddep.h. Of particular note is that the host version
+uses Ansi characters while the ReactOS version uses Unicode. So, the core
+source uses TCHARs. builddep.h depends on a preprocessor variable INFLIB_HOST
+which is defined when building the host version (inflib.mak) but not defined
+when building the ReactOS version (inflib.xml).
+The wrappers have "host" or "ros" in their filename. The library interface is
+"infhost.h" for the host version, "infros.h" for the ReactOS version.
