* especially to improve building on FreeBSD 11
* We need GNU Make, yet alone because Scintilla/Scinterm
needs it. We now document that dependency and added
an Autoconf check from the autoconf-archive.
We make sure that the build process is invoked with GNU make
by generating only GNUmakefiles.
The Makefile.am files have not been renamed, so this
change can be rolled back easily.
* Some GNU-Make-specific autoreconf warnings have still been
resolved. But not all of them, as this would have been
unelegant and we need GNU Make anyway.
* Declare ACLOCAL_AMFLAGS to appease autoreconf
* Added an explicit check for C++11 from the autoconf-archives.
In general we should support building with every C++11 compiler
that is sufficiently GNU-like.
* Do not use `sed` for inplace editing, as different sed-implementations
have mutually incompatible syntax for this.
Instead of declaring and checking a dependency on GNU sed,
we simply use SciTECO for the editing task.
This improves code portability on BSDs.
* Similarily, BSD/POSIX `cmp` is supported now.
This fixes the test suite on BSD without declaring a
dependency on the GNU coreutils.
* Simplified sciteco-wrapper generation.

* it turns out that option-like arguments could not be reliably passed to
SciTECO scripts for two reasons:
a) "--" arguments are not removed from argv by GOption if it detects
and following option-like argument.
"--" would thus be passed as a script argument which will disable
option parsing in scripts that interpret "--".
b) A script run via the Hash-Bang line "#!...sciteco -m" would
require an explicit "--" to turn of GOption parsing.
However it is __impossible__ to insert after the script file name
on UNIX.
* Therefore, SciTECO now removes leading "--" arguments left over by GOption.
* If possible (Glib >= 2.44), option parsing is performed in strict POSIX
mode which inhibits parsing after the first non-option argument.
This reduces the number of cases where an explicit "--" is required.
* --mung no longer takes an argument. Instead, the first non-option argument
is expected to be the script file name.
This looks weird at first but is more consistent with how other interpeters
work. Once we revise argument passing to scripts, the script name can also
be passed to the script which is more consistent with it being the first
non-option argument.
Also, with strict POSIX parsing, this fixed Hash-Bang lines since
the script file name constructed by the kernel will automatically switch
off option parsing, passing all option-like script arguments uninterpreted
to the script.
* Since we're supporting Glib < 2.44, the Hash-Bang lines are still broken
for certain builds.
Therefore, a wrapper script is installed to libexecdir (it never has to be
executed by users and Hash-Bang lines need absolute paths anyway) which
transparently inserts "--" into the SciTECO command line and should be used
as the interpreter in portable SciTECO scripts.
The wrapper script is generated and points to the exact SciTECO binary
installed. This is important when doing parallel installs of Curses and Gtk
binaries since each one will get its own working wrapper script.
The wrapper-script workaround can be removed once we depend on Glib >= 2.44
(some day...).
* The default /usr/bin/env Hash-Bang lines are no longer used in the
scripts since they are broken anyway (UNIX incl. Linux cannot pass
multiple arguments to the interpreter!).
Scripts that get installed will get a fixed-up Hash-Bang line referring
to the installed SciTECO binary anyway.
* Interface::main() has been renamed to Interface::init() and is optional
now. The Interface::main() method was introduced because of the misconception
that interfaces will find their options in the argv array and have to do
their own parsing.
This is wrong, since their option group already cares about parsing.
Therefore, gtk_init() does not have to called explicitly, too.

* the new "?" (help) command can be used to look up
help topics.
* help topics are index from $SCITECOPATH/women/*.woman.tec
files.
* looking up a help topic opens the corresponding "womanpage"
and jumps to the position of the topic (it acts like an anchor
into the document).
* styling is performed by *.woman.tec files.
* Setting up the Scintilla view and munging the *.tec file
is performed by the new "woman.tes" lexer.
On supporting UIs (Gtk), womanpages are shown in a variable-width
font.
* Woman pages are usually not hand-written, but generated from manpages.
A special Groff post-processor grosciteco has been introduced for this
purpose. It is much like grotty, but can output SciTECO macros for styling
the document (ie. the *.woman.tec files).
It is documented in its own man-page.
* grosciteco also introduces sciteco.tmac - special Troff macros
for controlling the formatting of the document in SciTECO.
It also defines .SCITECO_TOPIC which can be used to mark up
help topics/terms in Troff markup.
* Woman pages are generated/formatted by grosciteco at compile-time, so
they will work on platforms without Groff (ie. as on windows).
* Groff has been added as a hard compile-time requirement.
* The sciteco(1) and sciteco(7) man pages have been augmented with
help topic anchors.

* the `date` utility is now invoked by SciTECO which avoids automake
warnings because of $(shell). The command line should work on Windows
as well when SciTECO executes using cmd.exe (hopefully).
|
|
* this leads to frequent build failures since for some strange reason
automake/autoconf will not always regenerate config.h on its own
|
|
* The PACKAGE_URL_DEV is also mentioned in --help output and sciteco(1)

$SCITECOPATH on Windows
* $SCITECOCONFIG has been introduced, so have a macro-accessible location
for the profile, buffer session etc.
This is set to the program dir on Windows. That way, the config files
will be found, regardless of the current working dir, but it may also
be set up for Unix-like environments on Windows.
* $SCITECOPATH defaults to the program dir + "/lib" now on Windows.
* The default profile is now always called ".teco_ini". Also on Windows.
Platform differences like this would need to be documented.
* The sample teco.ini has been renamed to "sample.teco_ini" for clarity
