 .SH DESCRIPTION
 .B Xpresent
-is a library designed to interface the X Present
-Extension.
+is a library designed to interface the X Present Extension.
+The Present extension provides a way for applications to update their
+window contents from a pixmap in a well defined fashion, synchronizing
+with the display refresh and potentially using a more efficient
+mechanism than copying the contents of the source pixmap.
+The
+.B XPresentQueryExtension
+function checks if the X server specified by \fIdpy\fP supports the X Present
+extension.  If the server does not support the extension, it returns False.
+If the server does support the extension, it returns True, and sets the
+values of \fImajor_opcode_return\fP, \fIevent_base_return\fP, and
+\fIerror_base_return\fP if the pointers are not NULL.
+.PP
+Clients must call the 
+.B XPresentQueryExtension
+function to verify the server supports the extension before calling any other
+function for this extension.
+The
+.B XPresentQueryVersion
+function sets the values pointed to by \fImajor_version_return\fP and
+\fIminor_version_return\fP to the version of the extension supported
+by the X server specified by \fIdpy\fP.
+The
+.B XPresentQueryVersion
+function returns the version of the libXpresent library in use, as defined
+by the \fBPRESENT_VERSION\fP macro in <X11/extensions/Xpresent.h>.
