4 Given a "libname.map" file on standard input and a list or directory
5 of .d dependency files liblist produces:
6  a) without -l option, a library list ordered according to the libname.map,
7  giving a warning if conflicting dependencies are found in the .d files.
8  b) with -l option, another libname.map, ordered according firstly to the
9  original libname.map file, then reordered according to the dependencies
10  found in the .d files. This option is used for compiling the file
11  libname.map from all the dependencies.
12  c) with -m <lpath> option, the whole existing libraries list ordered
13  according to the libname.map, where libraries are placed in <lpath>.
14 The .d files are specified in the argument(s).
15 The libname.map is on standard input.
16 
17 Usage:
18  liblist *.d < libname.map
19  liblist -d <ddir> < libname.map
20  liblist -l *.d < libname.map
21  liblist -ld <ddir> < libname.map
22  liblist -l -d <ddir> < libname.map
23  liblist -m <lpath> < libname.map
24 where:
25  <ddir> is a directory name of a directory which is recursively
26  searched for dependency files
27  <lpath> is the path where libraries are located
