%%%     LaTeX bug report generator.
%%%     %%%%%%%%%%%%%%%%%%%%%%%%%%
%%%
%%%     Processing this file with LaTeX should produce
%%%     a file latexbug.msg in the current directory.
%%%
%%%     latexbug.msg may be used as a template for submitting bug
%%%     reports concerning files in the standard LaTeX distribution.
%%%
%%%     * Any bug report should include a small LaTeX test file
%%%       that shows the bug, and the log that LaTeX produces on the
%%%       test file.
%%%
%%%     * Reports should be in English.
%%%
%%%     * Reports should be as short as possible.
%%%
%%%     Please check before submitting a bug report that your format
%%%     is not more than two years old. New LaTeX releases occur at
%%%     regular intervals, and so your bug may be fixed in a later
%%%     release.
%%%
%%%     Completed bug report forms should be submitted to:
%%%     latex-bugs@latex-project.org
%%%
%%%     Please:
%%%     use the synopsis text as the `Subject' line of the message.
%%%     ===========================================================
%%%
%%%     For example:
%%%     Subject: \verb does not work inside \caption
%%%
%%%     So that your message has an identifying subject. 
%%%     Do not use subject lines such as `LaTeX bug' as this does not
%%%     help us to identify your message.
%%%
%%%     To follow up an existing report, include the bug reference, e.g.
%%%     "latex/1234: ", preceding the subject text.
%%%
%%%     Configuring latexbug
%%%     ====================
%%%     If you often test early release of LaTeX packages, and feel that
%%%     you may need to use this program often, you may create a file
%%%     latexbug.cfg
%%%     This should contain the answers of certain standard questions.
%%%     (Such as your name and email address.)
%%%
%%%     Currently the responses that may be stored in latexbug.cfg are:
%%%     name address organisation and interactive.
%%%     (If organisation is not set in the .cfg file latexbug does not
%%%     prompt for it, as this is not vital information.)
%%%
%%%     For example, a personal latexbug.cfg could look like
%%%     
%%%     \def\name{My Real Name}
%%%     \def\address{name@some.place}
%%%     \def\organisation{My Institution}
%%%     \def\interactive{y}
%%%     
%%%     A site latexbug.cfg might just set the \organisation, leaving
%%%     the personal details to be filled in interactively by the user.
%%%     
%%%  }
%%% ====================================================================
