1) Rename cp_HLPflag -> cp_follow for consistency.
2) Use function-pointers for stat to clear up the code.
3) BUGFIX: TERMINATE THE RESULT BUFFER OF READLINK !!!
It's something I noticed earlier and it actually lead to some
pretty insane behaviour on our side using glibc (musl somehow
magically solves this).
Basically, symlinks used to contain the data of the file they
pointed to. I wondered for weeks where this came from and now
this has finally been solved.
4) BUGFIX: Do not unconditionally unlink target-files. Even GNU
coreutils do it wrong.
The basic idea is this:
If fflag == 0 --> don't touch target files if they exist.
If fflag == 1 --> unlink all and don't error out when we try
to unlink a file which doesn't exist.
5) Use estrlcpy and estrlcat instead of snprintf for path building.
6) Make it clearer what happens in preserve.
sbase - suckless unix tools
===========================
sbase is a collection of unix tools that are inherently portable
across UNIX and UNIX-like systems.
The following tools are implemented ('*' == finished, '#' == UTF-8 support,
'=' == implicit UTF-8 support, '|' == audited, () == petty flag):

The complement of sbase is ubase[1] which is Linux-specific and
provides all the non-portable tools. Together they are intended to
form a base system similar to busybox but much smaller and suckless.
Building
--------
To build sbase, simply type make. You may have to fiddle with
config.mk depending on your system.
You can also build sbase-box, which generates a single binary
containing all the required tools. You can then symlink the
individual tools to sbase-box or run: make sbase-box-install
Ideally you will want to statically link sbase. If you are on Linux
we recommend using musl-libc[2].
Portability
-----------
sbase has been compiled on a variety of different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.
Various combinations of operating systems and architectures have also
been built.
You can build sbase with gcc, clang, tcc, nwcc and pcc.
