-@command{dlltool} may be used to create the files needed to build and use
-dynamic link libraries (DLLs).
+@command{dlltool} is used to create the files needed to create dynamic
+link libraries (DLLs) on systems which understand PE format image
+files such as Windows. A DLL contains an export table which contains
+information that the runtime loader needs to resolve references from a
+referencing program.
+
+The export table is generated by this program by reading in a
+@file{.def} file or scanning the @file{.a} and @file{.o} files which
+will be in the DLL. A @file{.o} file can contain information in
+special @samp{.drectve} sections with export information.
