FRIGN 7d3e9c6e88 Resolve escape characters in tr(1)
This is one aspect which I think has blown up the complexity of many
tr-implementations around today.
Instead of complicating the set-theory-based parser itself (he should
still be relying on one rune per char, not multirunes), I added a
preprocessor, which basically scans the code for upcoming '\'s, reads
what he finds, substitutes the real character onto '\'s index and shifts
the entire following array so there are no "holes".

What is left to reflect on is what to do with octal sequences.
I have a local implementation here, which works fine, but imho,
given tr is already so focused on UTF-8, we might as well ignore
POSIX at this point and rather implement the unicode UTF-8 code points,
which are way more contemporary and future-proof.

Reading in \uC3A4 as a an array of 0xC3 and 0xA4 is not the issue,
but I'm still struggling to find a way to turn it into a well-formed
byte sequence. Hit me with a mail if you have a simple solution for
that.

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:

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
--------

You need GNU make to build sbase on OpenBSD.

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.

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.
