+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+\`configure' configures vlna 1.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+			  (and sometimes confusing) to the casual installer
+  --disable-dependency-tracking  speeds up one-time build
+  --enable-dependency-tracking   do not reject slow dependency extractors
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+\N{1}{1}PROGRAM VLNA.
+Program čte vstupní textový soubor a nahrazuje za specifikovanými
+jednopísmennými slovy (např.~v, k, u) mezery symbolem \uv{\.{\char126}}. To
+zabrání při následném zpracování \TeX{}em zlomit řádek na nevhodných
+místech, která jsou v rozporu s typografickou normou.
+
+Program sestává z těchto hlavních celků:
+\Y\B\X3:Hlavičkové soubory k načtení\X\6
+\X4:Globální deklarace\X\6
+\X6:Pomocné funkce\X\6
+\X26:Vlnkovací funkce \PB{\\{tie}}\X\6
+\X5:Hlavní program\X\par

+Program čte z~příkazového řádku postupně (nepovinné) parametry,

+souborů.
+\begitems
+* \.{-f} \dots\ program pracuje jako filtr (viz sekce \PB{$\X11:Zpracování
+souborů\X$}). Není-li tento parametr použit, program pracuje v tzv.
+standardním režimu, kdy jednotlivé soubory jsou vstupní i výstupní.
+* \.{-s} \dots\ program nevypíše \PB{\.{BANNER}}, ani sumarizaci, ani varování,
+při nichž není program předčasně ukončen.  Všechny tyto výpisy
+směřují do \PB{\\{stderr}}, takže pokud program pracuje v režimu \uv{filtr},
+není nutné tento parametr použít.
+* \.{-r} \dots\ program maže pracovní soubor (soubory), které vytváří
+ve standardním režimu (tj. není použit \.{-f}). V reřimu filter nemá
+tento parametr vliv.
+* \.{-v} \dots\ parametr definuje skupinu písmen, které budou
+interpretovány jako neslabičné předložky.
+Např. \.{-v KkSsVvZzOoUuAI}. Pokud není parametr uveden, je použita
+skupina uvedená v tomto příkladě.
+* \.{-m} \dots\ program neprovádí kontrolu math/text módů, tj. vlnkuje i
+uvnitř matematického módu \TeX{}u. (Implicite tam nevlnkuje).
+* \.{-n} \dots\ prorgram neprovádí kontrolu verbatim módu, tj. vlnkuje i
+uvnitř verbatim módu definovaném běžnými prostředími. Imlicite ve
+verbatim prostředí nevlnkuje.
+* \.{-l} \dots\ La\TeX{} režim. Při kontrole text-math-verbatim módů jsou
+brány v úvahu další sekvence, obvyklé v La\TeX{}ových dokumentech.
+* \.{-w} \dots\ WEB režim. Ohraničení verbatim módu je doplněno znaky
+používanými v dokumentech WEB (např. tento dokument). Důsledek: program
+vlnkuje dokumentační část každé sekce, ale nikoli kód.

+\N{1}{15}Patterny.  Abychom mohli účelně definovat chování programu
+v~různých situacích, zavedeme datovou strukturu \PB{\.{PATTERN}}. Zhruba
+řečeno, budeme sledovat vstup znak po znaku a pokud bude část vstupu
+souhlasit s~definovaným patternem, provedeme námi požadovanou
+akci. Například nejčastější aktivitu, přidání vlnky uvnitř řádku,
+spustíme v~okamžiku, kdy vstupní text odpovídá patternu \uv{\.{\ (v\
+p}}, kde \uv{\.{\ }} znamená jedna nebo více mezer a tabelátorů,
+\uv{\.{(}} je nula nebo více otevíracích závorek všeho druhu,
+\uv{\.{v}} znamená jedno písmeno z~množiny předložek (viz \PB{\\{charset}}) a
+\uv{\.{p}} zde znamená libovolné písmeno. Příklad zde není zcela přesný.
+Přesně jsou všechny patterny pro náš program definovány v~závěrečných
+sekcích tohoto povídání.
+
+Pattern bude znamenat konečnou sekvenci tzv. pozic patternu (\PB{\.{PATITEM}}).
+Cykly uvnitř pozic pro jednoduchost nepřipustíme. Každá pozice obsahuje
+řetězec znaků, uvažovaný pro danou pozici (v~příkladu pozice~\uv{\.{\ }} by
+obsahovala mezeru a tabelátor, zatímco pozice \.{v} odpovídá \PB{\\{charset}}).
+Každá pozice má svůj přepínač (\PB{\\{flag}}), který obsahuje informaci o~tom,
+zda shodu testovaného znaku s~některým prvkem v~množině znaků
+budeme považovat za úspěch či neúspěch a zda pozice se ve zkoumaném
+řetězci může vyskytovat právě jednou nebo opakovaně. Jako druhý případ
+stačí implementovat \uv{nula nebo více} protože \uv{jedna nebo více} lze
+popsat pomocí dvou pozic, první \uv{právě jednou} a následující \uv{nula
+nebo více}. Jednotlivé pozice jsou zřetězeny ukazatelem \PB{\\{next}}, poslední
+pozice má \PB{$\\{next}\E\NULL$}. Stejně tak jednotlivé patterny budeme
+sestavovat do seznamů a budou rovněž zřetězeny ukazatelem \PB{\\{next}}.
+
+Pattern kromě řetězu pozic obsahuje ukazatel na funkci (proceduru) \PB{%
+\\{proc}},
+která se má vykonat v~případě, že testovaný řetězec vyhovuje patternu.

+\M{16}Deklarujeme některé globální proměnné pro práci s~patterny. \PB{\\{lapi}}
+je pole
+obsahující ukazatele na aktuální pozice v~otevřených patternech. Říkáme,
+že \uv{pattern je otevřen}, pokud zkoumaný řetězec s~ním {\it začíná\/}
+souhlasit. Pattern se uzavře, pokud nastane jedna ze dvou možností:
+zkoumaný řetězec s~mím souhlasí až do konce (v~takovém případě se provede
+procedura \PB{\\{proc}}), nebo při vyšetřování dalších znaků ze zkoumaného
+řetězce přestane řetězec s~patternem souhlasit.
+
+V~dané chvíli může být pattern otevřen několikrát. Např. pattern \.{abac}
+je při stringu \.{aba} při výskytu druhého \.{a} otevřen podruhé. Proto
+pole obsahuje ukazatele na právě aktuální pozici patternu a nikoli na
+pattern jako takový.
+
+V~poli \PB{\\{lapi}} budou na počátku samá \PB{$\NULL$} (to se při překladu
+inicializuje
+samo) a přemazání ukazatele na pozici konstantou \PB{$\NULL$} budeme považovat
+za zavření patternu. Vedle pole \PB{\\{lapi}} souměrně udržujeme pole \PB{%
+\\{lapt}},
+do něhož budeme ukládat ukazatele na odpovídající otevřený pattern. Tuto
+informaci použijeme v~případě, že potřebujeme např, znát \PB{\\{proc}}
+patternu.
+
+\PB{\\{listpatt}} bude ukazovat na začátek aktuálního seznamu patternů. Seznamy
+budeme mít dva. Jeden se použije, nacházíme-li se mimo komentář a druhý
+v~případě, že se nacházíme v~prostoru \TeX{}ovského komentáře (tj. za
+procentem). Starty těchto seznamů patternů jsou \PB{\\{normallist}} a
+\PB{\\{commentlist}} a aktivní \PB{\\{listpatt}} má vždy jednu z~těchto dvou
+hodnot.
+
+Proměnné \PB{\\{lastpt}} a \PB{\\{lastpi}} použijeme pro budování řetězové
+struktury
+patternů.
+
+Proměnná \PB{\|c} obsahuje právě testovaný znak ze vstupu (který se rovněž
+přepíše do bufferu \PB{\\{buff}}). Z~bufferu občas ukládáme data do výstupního
+proudu. Děláme to ale vždy jen v~okamžiku, kdy není otevřen žádný
