4Given a "libname.map" file on standard input and a list or directory
5of .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>.
14The .d files are specified in the argument(s).
15The libname.map is on standard input.
16
17Usage:
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
24where:
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
