-Rules for building IMAP
------------------------
-
-Note 1:  You *must* use NT's cmd.exe for this job;  4NT.exe will NOT work properly.
-Note 2:  During the entire build process, you can ignore warnings about
-         inconsistent DLL linkage.
-
-- Open IMAP under php_build.  Rename this directory to 'IMAP'.
-- Change to the IMAP directory.
-- Edit .\src\osdep\nt\makefile.nt:
-  Search for '/MT', and change it to '/MD'.  If you're compiling in DEBUG mode,
-  use '/MDd' instead.
-  Search for 'ERASE'.  Comment out the line that contains the ERASE command.
-- Run 'nmake nt'
-
----Begin Win2K only---
-- At some point, the build will fail.  Rerun 'nmake nt'.
-- After a while, the build will fail again, failing to find auths.c.
-- Change directory to 'c-client'
-- Create an a file named auths.c, that includes the following line:
-  #include "auth_md5.c"
-- Run 'nmake -f makefile.nt'
----End Win2K only---
-
-At this point (even if the last build apparently failed), you should have the
-client library ready (cclient.lib).
-
-Start Visual Studio, load php_modules.dsw, select the IMAP projects, and build
-it.
