- * Error messages TODO describe them here
+ * Error messages -> when an error occurs, TeX usually writes something
+   like "! Some error" followed by lines that resemble a stack trace of
+   where the error occurred. For example, this input:
+
+       Some text \blah, something else
+
+   would result in
+
+       ! Undefined control sequence.
+       l.5 Some text \blah
+                          , something else
+
+   With option -file-line-error, the exclamation is replaced by an
+   indication like "filename:linenum:".
+
+   The "stack trace" is comprised of pairs of lines. By default, LaTeX
+   only shows the last pair (depending on \errorcontextlines) and, when
+   there are more lines, they are replaced by a line with " ..." (right
+   after the line starting with "!"). In each pair of lines, the first
+   one indicates the line content leading up to the error and the
+   second one shows the subsequent content. The first line is at most
+   half_error_line characters long (default 50) and the second line
+   is at most error_line characters long (default 79). The second line
+   is indented to start after the end of the first, as in the example
+   above. If the content of a line does not fit, a part of it (the
+   beginning for the first line and the end for the second line) may
+   be replaced by "...".
+
+   LaTeX errors usually follow the format
+
+       ! LaTeX/Package/Class BLAH Error: some description
+       See the BLAH documentation for explanation.
+       Type H <return> for immediate help.
+        ...
+       l.5 First error line
+                           second error line
+
+   In errorstop mode, such errors are followed by a "?" prompt.
+
+   Finally, runaway arguments have a different format:
+
+       Runaway argument?
+       some text\ETC.
+       ! SOMETHING ended...
 
 To complicate things, TeX by default wraps (breaks) any line longer
 than max_print_line characters (by default, 79). Since some messages
