- # Script to compile a resource file for a DLL if there is a .rc file
- # for it. The resource source file is supposed to contain a version
- # info section, that uses the string BUILDNUMBER as the least
- # significant part of the version numbers. This script replaces that
- # string with a "build number" before compiling the binary resource
- # file. The build number is kept between builds in a "stamp" file, and
- # incremented each time. (If there is no stamp file, build number 0 is
- # used.) The intention is that only the "official" maintainer of a DLL
- # keeps such a stamp file, and thus the DLLs he releases have
- # increasing version number resources, which can be used by an
- # installer program to decide whether to replace an existing DLL with
- # the same name.
-
- # This is just my (tml@iki.fi) idea, if somebody comes up with a
- # better way to generate version number resources, don't hesitate to
- # suggest.

- # The command line arguments are:
- # $1: the name of the .rc file to check
- # $2: the name of the resource object file to produce, if the rc file exists
-
- # Check if we have a resource file for this DLL.

- resfile=$2

- # Check if we have a build number stamp file.
