% The macros in this file are used for recognizing the componants of
% of a  syllable and building the syllable from constituent symbols
% from the current  font. This file also contains macros for 
% processing various accents.
% When tlxlate.tex recognizes a consonant X the macro \tlcbX is
% invoked. When tlxlate.tex recognizes a vowel Y the macro \tlvoY
% is invoked. \tlcbX invokes the macro \tlconsonant with certain     
% parameters concerning X. Similarly \tlvoY invokes the macro
% \tlvowel with certain parameters concerning Y. \tlconsonant
% and \tlvowel are key macros.   
% \tlcosonant:
%     If the consonant is the base consonant
%      then
%         set appropriate flags. initialize syllable box with
%         the base consonant.
%      else
%         (this is a consonant conjunct that modifies the last
%         base consonant.) save the token (\tlccX)on the consonant
%         conjunct list. This list is executed after base consonant
%         is modified by a vowel. 
%    endif
%
% \tlvowel:
%    If the vowel is independent(stand alone) 
%     then
%        syllable consists of just this vowel.
%        place this vowel in the syllable box.
%     else
%        (this is a vowel modifier.)
%        check if the base consonant when modified by this vowel
%            needs any special handling.
%        If yes then invoke the macro \tlcvXY macro
%               else invoke the standard vowel modifier macro(\tlvmY)
%        execute macros on consonant conjunct list.
%    endif
%        add space in the syllable box. 
%        if preceeded by a box then insert a discretionary hyphen.
%        release the syllable box.
%
% processing accents:
%   when tlxlate.tex reads an accent it invokes a macro(there is a
%   macro for each accent) in this file. Typically processing an
%   accent involves pulling off the last box and applying the
%   accent.
%
\input tloffsets
%macro naming conventions:
%macro names begin with either tl or zz. Macros that begin with zz are those
%that are invoked after declaration of active characters used in
%transliteration.
%\tlbmxxx    These are used for box manipulation
%\tlcbxxx    When a consonant is read these macros are invoked(consonant base)
%\tlvmxxx    These process vowel modifiers
%\tlvoxxx    When a vowel is read these macros are invoked
%\tlccxxx    Process consonant conjuncts
%\tlcvxxx    Processes consonant+vowel combination. Existance of this
%                     macros indicates that the con.+vowel combination
%                     needs special treatment. The name of this macro is
%                     \tlcv+consonant+vowel
%Following are the declarations for fonts. If some of these are
%not available then those statements must be commented out.
%Else TeX will complain that 'TFM file is not found'.

%*** Hyphenation and spacing
% Guiding principle for hyphenation is that a syllable should not be
% broken across lines. Since all syllables are built in boxes and
% boxes are not broken up for hyphenation we are ensuring that this
% principle is followed. But then we are not giving enough freedom
% to TeX for breaking lines into paragraphs. So what we do is suggest
% some places where lines can be broken. This is done by inserting
% discretionary hyphens. Discretionary hyphens are inserted between
% syllables within a word. The problem is that we know we processing a 
% syllable but we do not know if this is preceeded immediatly
% by a syllable. It is not easy to determine either. The device
% that is used decide if current syllable is preceeded by a syllable
% is to extract lastbox. If lastbox is not void then insert a
% discretionary hyphen. Since all syllables are output as boxes
% we will always have a discretionary hyphen between syllables.
% But if the lastbox is not void then we can not say that the lastbox
% is indeed a syllable box. One example is paragraph indent box.
% This is not a serious problem.(Paragraph indentation appears at
% the begining of a line, hence is hardly a candidate for hyphenation.)
% Note that punctuation, digits and other non-syllable characters
% are not held in boxes and hence lastbox operation returns void.
% See TeX Book for details about \lastbox.
%
% For the purpose of readability \tlbmspace space is added following
% a syllable. This is not necessary in English because each symbol in
% the font represents a standalone symbol.Spacing is provided in
% the font itself. Whereas in Telugu font most symbols are parts
% for composing syllables. Spacing is not provided in the font
% for these symbols. 
%\tlbmskip introduces blank space after a syllable. Depending on context
% a discretionary hyphen is added before the syllable.

%*** macros to process consonants
%\tlconsonanant is called whenever a consonant is encountered
% the consonant could be base consonant(first consonant of a syllable)
% or a conjunct. If base consonant then 1. set base consonant seen flag
% to yes 2. put the consonant in \syl box 3. place the name of the
% consonant in the token list \cbtok. This is used by \tlvowel to
% form the macro name to process consonant+vowel
% If consonant conjunct then store the macro name to process the conjunct 
% in the token list \cctok. If the consonant is 'x' then the macro to
% process the conjunct form of 'x' is \tlccx
% parameters:
%   #1   name of the consonant
%   #2   position in the font( of base consonant)
%   #3   offset from the left edge of the bounding box for the
%            base consonant. Used for alligning vowel modifiers
%            Received as \xxxxOFFSETA.
%   #4   offset from the left edge of the bounding box for the
%            base consonant. Used for alligning consonant conjuncts
%            Received as \xxxxOFFSETB.
%   #5   This is either 0 or 1. 1 indicates that when modified
%            by vowel 'a' there is a hat (a check mark) on the top
%            else no hat.
%   #6    If this consonant needs special treatment when modified by certain

%            those groups of vowels otherwise this parameter is 113

%*** macros to process vowels
%\tlvowel is called to complete box building. This macro is called
%  when a vowel is read. The vowel could be a stand alone vowel or
%  it could modify base consonant. In the latter case following steps
%  are executed.  a) check if the particular combination of Consonant
%  and vowel need special handling. That is if \vowprime divides \consprime
%  evenly. If yes then form the macro name
%  and invoke it. Else invoke the handler for the particular vowel.
%   (An alternate way of implementing this would be to check if \tlcvCV
%    macro exits. If yes then invoke this macro)
%  b) Then process consonant conjucts. The list of consonant conjunct 
%  macros is built in \cctok. 
% Parameters:
%   #1. code for the vowel (This  is not used.)
%   #2. name of the vowel
%   #3. position of the vowel in the font
%   #4. vowels are partitioned into 5 groups. Each group gets a different prime
%        number.The groups/codes are{A-2},{i,I-3},{u,U-5},{o,O-7},
%                                 {ow-11},{others-109}
%        The groups are formed such that if a consonant when combined with a
%        member of a group needs special handling then so with other vowels
%        in the same group.
% After syllable is formed some space is inserted(for readability)
