The new build instructions are:
$ ./configure && make && sudo make install
The configure script tries to auto detect support for various libraries
and compiler options. These choices can be overwritten by explicitly
specifing --{en,dis}able-{lua,selinux,acl}. See ./configure --help for
all supported options.
The configure script generates config.mk which should allow portable
(among GNU and BSD make) Makefiles. Manually editing config.mk is
still supported.

They do not seem to be supported on all platforms (e.g. FreeBSD).
Users who know what they are doing can still provide them via the
regular $CFLAGS mechanism. Eventually these should be tested by a
handwritten configure script and added to config.mk iff they are
supported by the toolchain.
|
|
These are picked-up by configure when building dependencies
during make standalone.

Lua support can now be disabled at compile time using:
$ make CONFIG_LUA=0
This commit also adds an initial Lua API and provides a few
default hooks.
We now also require Lua >= 5.2 due to the uservalue constructs.
In principle the same functionality could be implemented using
function environments from Lua 5.1.

For musl this is a nop, it contains the relevant code in libc
and provides and empty libdl archive for compatibility.
However certain glibc based system need it.

Make lpeg module table explicitly global, which should work
with the different module loading semantics.
|
|
Add separate per library {C,LD}FLAGS and use default values
from pkg-config to allow for finer control.
Disable pkg-config by setting PKG_CONFIG_PATH= PKG_CONFIG_LIBDIR=
Override flags completely by specifying them as arguments to make:
$ make CFLAGS_CURSES="your custom flags for curses"
Also introduce a new, experimental Makefile target standalone. It
tries to build a self contained statically linked vis binary. All
dependencies (musl, ncurses, termkey, lua, lpeg) are build from
source. Lua is patched to include lpeg as a statically built module.

Should hopefully fix build on Mac OS X.

Key bindings are now specified as symbolic key strings, this
will eventually allow run time configurable key mappings.
This introduces a bulid time dependency on libtermkey which
can be found at:

Try to do an atomic save using rename(2) unless
* the file is a symbolic link
* the file is a hard link
* file ownership can not be preserved
* file group can not be preserved
* POSXI ACL can not be preserved (if enabled)
* SELinux security context can not be preserved (if enabled)
in which case the file is overwritten in place. However a failure
to do so results in data loss.
Closes #47.

Unfortunately this breaks support for BSD make.
