Meta wlx plug-ins (wlm) are used in wlx2far for defining
if file supports by fixed wlx plugin. For this purpose in
meta wlx plug-in there are 2 exported functions:

void ListGetExtensions(char* extbuffer,int bufferlength) -
     Function returns masks of files which are supported
     wlx by a corresponding wlx plug-in.
int  ListIsSupported(const char *FileName,const char *Buffer,DWORD BufferSize) -
     Function checks if the concrete file supports in wlx
     plug-in. Meta plug-in receives a name of a file and
     an initial file content fragment of size BufferSize.
     Return value is 0 if file doesn't support.

At the analysis of suitability of a file to an available
list wlx plug-ins and allocation of one of them for display
of a file wlx2far uses a following algorithm:
1) Check of masks in wlx2far which are kept in "wlx2far.ini".
   It is consecutive for all wlx plug-ins
2) Check of masks received from ListGetExtensions () for each
   of available wlx plug-ins
3) Analysis of result ListIsSupported () for each of available
   wlx plug-ins

For work with meta wlx plug-in its name should be same as
well as wlx plug-in, but with wlm extension:

myplugin.wlx - regular wlx plug-in
myplugin.wlm - 易    .

For work the majority wlx plug-ins it is possible to use
standard meta wlx a plug-in. This meta plug-in connects
with corresponding wlx plug-in the list of extensions which
are in a file "meta.ini". Having renamed "Meta.wlm" with
yours wlx a plug-in and editing "meta.ini", you can connect
meta plug-in with any wlx plug-in.
