30 The idea is that this file will eventually have wrappers around all
31 important system calls in samba. The aims are:
33 - to enable easier porting by putting OS dependent stuff in here
35 - to allow for hooks into other "pseudo-filesystems"
37 - to allow easier integration of things like the japanese extensions
39 - to support the philosophy of Samba to expose the features of
40 the OS within the SMB model. In general whatever file/printer/variable
41 expansions/etc make sense to the OS should be acceptable to Samba.
