### musl-fts The musl-fts package implements the `fts(3)` functions `fts_open`, `fts_read`, `fts_children`, `fts_set` and `fts_close`, which are missing in musl libc. It uses the NetBSD implementation of `fts(3)` to build a static library `/usr/lib/libfts.a` and the `/usr/include/fts.h` header file.
