+
+	How to use:
+		1. Add new export function 'Meta_PExtGiveFnptrs' to your plugin file.
+		   'Meta_PExtGiveFnptrs' will be called right after 'Meta_Query' call.
+		2. Meta_PExtGiveFnptrs is called with interface version 'META_PEXT_VERSION'
+		   and pointer to extension function table.
+		3. Meta_PExtGiveFnptrs should return plugin's interface version.
+		4. !NOTE! Metamod will not stop loading plugin even if plugin returns 
+		   interface version greater than current. Plugin should disable itself in
+		   this kind of situation.
+	
+	Example:
+		#include "mm_pextensions.h"
+		
+		pextension_funcs_t *gpMetaPExtFuncs;
+		
+		int Meta_PExtGiveFnptrs(int interfaceVersion, pextension_funcs_t *pMetaPExtFuncs) {
+			if(interfaceVersion < META_PEXT_VERSION) {
+				LOG_DEVELOPER(PLID, "Error! Metamod is too old, please update!");
+				gpMetaPExtFuncs = NULL;
+			
+				return(META_PEXT_VERSION);
+			}
+			
+			gpMetaPExtFuncs = pMetaPExtFuncs;
+			
+			return(META_PEXT_VERSION);
+		}
+	
+	Callback functions:
+		- int PEXT_LOAD_PLUGIN_BY_NAME(PLID, const char *cmdline, PLUG_LOADTIME now, void **plugin_handle);
+			Parses 'cmdline' as metamod would parse 'meta load <cmdline>' and loads found 
+			plugin. If 'plugin_handle' is set, metamod writes module handle of loaded 
+			plugin at it.
+			Returns zero on success.
+			For error codes see 'META_ERRNO' in 'types_meta.h'.
+		
+		- int PEXT_UNLOAD_PLUGIN_BY_NAME(PLID, const char *cmdline, PLUG_LOADTIME now, PL_UNLOAD_REASON reason);
+			Parses 'cmdline' as metamod would parse 'meta unload <cmdline>' and 
+			unloads found plugin.
+			Returns zero on success.
+			For error codes see 'META_ERRNO' in 'types_meta.h'.
+		
+		- int PEXT_UNLOAD_PLUGIN_BY_HANDLE(PLID, void *plugin_handle, PLUG_LOADTIME now, PL_UNLOAD_REASON reason);
+			Unloads plugin with 'plugin_handle'.
+			Returns zero on success.
+			For error codes see 'META_ERRNO' in 'types_meta.h'.
+		
+		!NOTE! Plugin cannot unload itself!
