% slatex.tex. Change LaTeX such that national characters '}', '{', '|',
% ']', '[' and '\' have no special meaning and install the Swedish
% symbols for these characters.

% To accomplish this the TeX special characters '\', '{' and '}' are
% replaced with '!', '<' and'>' respectively. Furthermore the LaTeX
% optional grouping characters '[' and ']' are substituted for '(' and ')'.

% LaTeX makes special use of '(' and ')' in coordinates so the coordinate
% delimiters are changed to '"' such that what used to be (x,y) is now "x,y".
% Also '|' in array environments is substituted for ':'. The .sty files
% for the modified LaTeX uses the suffix .sst.

% lplain.tex and latex.tex are left untouched except for the very last lines
% in lplain where this file is included. The macros needing attention are
% copied to the appropriate file, see below, where the substitutions are
% carried out. Several files focusing on one substitution are used to
% make it easy to change the choise of replacement character. However some
% of the changes migrates to the following files (especially the parens).

\makeatletter	% temporarily make at signs behave as letters

\input paren.tex

% parens must now replace brackets (to print brackets us \lbrack etc.)
% in all files below.

\input dquote.tex

\input sst.tex

\input bar.tex

\input bang.tex

\input swedish.tex

% Now '!', '<' and '>' has to be used instead of '\', '{' and '}'.

!input write.tex

% The following macro sets up the verbatim environment

!begingroup !catcode `|=0 !catcode `(= 1
!catcode`)=2 !catcode `!<=12 !catcode `!>=12
!catcode`!!=12 |gdef|@xverbatim#1!end<verbatim>(#1|end(verbatim))
|gdef|@sxverbatim#1!end<verbatim*>(#1|end(verbatim*))
|endgroup

!makeatother	% at signs are no longer letters
