Rename Buttress to Halibut. I _think_ I've caught everything in this pass.


git-svn-id: svn://svn.tartarus.org/sgt@1800 cda61777-01e9-0310-a592-d414129be87e
Upgrade to Halibut xhtml backend, to allow leaf_level to be zero (in
which case the whole of the HTML output will be in a single file,
currently called Manual.html in the absence of configurability).
This includes the index, if present.


git-svn-id: svn://svn.tartarus.org/sgt@1831 cda61777-01e9-0310-a592-d414129be87e
Slightly improve the handling of headings in HTML single-file mode.


git-svn-id: svn://svn.tartarus.org/sgt@1832 cda61777-01e9-0310-a592-d414129be87e
Add `topclean' target to the top-level Makefile, to remove the
output from running Halibut on a test input file.


git-svn-id: svn://svn.tartarus.org/sgt@1833 cda61777-01e9-0310-a592-d414129be87e
Fix the bug in the text back end whereby bulletted paragraphs' width
failed to be decreased to compensate for the additional indent.


git-svn-id: svn://svn.tartarus.org/sgt@1834 cda61777-01e9-0310-a592-d414129be87e
Arrange for multiple \cfg, \IM and \BR paragraphs to not require
blank-line separators (config directives visually _want_ to be in a
single chunk).


git-svn-id: svn://svn.tartarus.org/sgt@1837 cda61777-01e9-0310-a592-d414129be87e
Add configurability for the suffix after the section number and
before the section title (the ": " in "Section 1: Introduction").


git-svn-id: svn://svn.tartarus.org/sgt@1838 cda61777-01e9-0310-a592-d414129be87e
Add configurability for section heading formats, in much the same
way as bk_text already does it (you can choose to have or not have
the "Section" at the start, and you can configure the suffix between
number and title).


git-svn-id: svn://svn.tartarus.org/sgt@1839 cda61777-01e9-0310-a592-d414129be87e
Just had a play with this newfangled `valgrind' memory debugger
thingy, which seems moderately cool and has reported a few very
small memory leaks. Now apparently fixed.


git-svn-id: svn://svn.tartarus.org/sgt@1863 cda61777-01e9-0310-a592-d414129be87e
Of course, when I start freeing things in response to valgrind's
complaints, it would probably help if I arranged that those things
had been _allocated_ in all cases, otherwise we merely exchange a
memory leak for a core dump. Duh.


git-svn-id: svn://svn.tartarus.org/sgt@1916 cda61777-01e9-0310-a592-d414129be87e
WinHelp backend segfaults when it finds a nonexistent cross-
reference. (The broken link will already have been reported in the
mid-end, but this won't inhibit output generation, so the onus is
still on us to at the very least not go *crash*.)


git-svn-id: svn://svn.tartarus.org/sgt@2507 cda61777-01e9-0310-a592-d414129be87e
Man-page back end for Halibut. Also, a couple of additional markup
features commonly used in man pages: (a) the ability to nest
paragraph breaks, code paragraphs and other lists inside list items,
and (b) description lists as normally used in man pages to describe
command-line options.


git-svn-id: svn://svn.tartarus.org/sgt@3954 cda61777-01e9-0310-a592-d414129be87e
Oops, nearly forgot. Nesting one numbered list inside another should
not break the numbering of the outer one!


git-svn-id: svn://svn.tartarus.org/sgt@3955 cda61777-01e9-0310-a592-d414129be87e
Cleanups to complete the man page backend. Also, an additional new
markup feature: a \c line in a code paragraph can now be followed by
an optional \e line indicating emphasised bits of its preceding \c.
This allows discretionary bolding and (italic/underline) emphasis
within code paragraphs, but without introducing an escape character
or breaking any existing input files. Users are warned that not all
backends are required to actually render these hints, and so they
should avoid depending on them 100% to convey semantic information
unless they know they're writing for a restricted range of backends.


git-svn-id: svn://svn.tartarus.org/sgt@3965 cda61777-01e9-0310-a592-d414129be87e
Apparently we must include the .TH directive in a man page even when
there's nothing to go in it.


git-svn-id: svn://svn.tartarus.org/sgt@3977 cda61777-01e9-0310-a592-d414129be87e
Add a \quote{...} directive, working like <blockquote> in HTML.


git-svn-id: svn://svn.tartarus.org/sgt@3978 cda61777-01e9-0310-a592-d414129be87e
First instalment of a manual for Halibut. This lot covers the
(nearly nonexistent) invocation syntax and the input format.


git-svn-id: svn://svn.tartarus.org/sgt@3979 cda61777-01e9-0310-a592-d414129be87e
Obsoleted the `\preamble' command. Preamble text is now taken to be
any ordinary displayable paragraph(s) appearing before the first
chapter heading, meaning in particular that you can put lists, code
paragraphs etc in preambles. Of course, `\preamble' is still
supported for backwards compatibility, but it's now a zero-effect
paragraph marker.


git-svn-id: svn://svn.tartarus.org/sgt@3981 cda61777-01e9-0310-a592-d414129be87e
Introduce \. as a NOP command. The purpose of this is to act as a
zero-width delimiter between a macro invocation and text beyond it,
so that you can define (say) a macro which expands to a Euro sign
and then write `\eur\.2500' to avoid having space between the Euro
sign and the number.


git-svn-id: svn://svn.tartarus.org/sgt@3982 cda61777-01e9-0310-a592-d414129be87e
Second instalment of the manual: added a chapter on output formats.
I _think_ the manual now contains all the information a user should
need, even if not yet in an optimal order for a beginner to learn
from.
