§5.  This is a more elaborate form of the standard StandardProblems::sentence_problem,
+used when an assertion sentence has gone wrong. Experience from the early
+builds of the Public Beta showed that many people tried syntaxes which
+Inform did not recognise, and which cause Inform to misread the primary
+verb of the sentence. It would then issue a Problem — because the sentence
+would be peculiar — but this problem report would itself be odd, and
+make little sense to the user. So we look to see if the current sentence
+is an assertion with a primary verb: and if it is, we hunt through it
+for alternative verbs which might have been intended, and try to produce
+a message which diagnoses the problem rather better.

 @h Problem quotations.
-Problem messages are printed using a printf-like formatting system.
-Unlike printf, though, where |%s| means a string and |%d| a number, here
-the escape codes do not indicate the type of the data: they are simply
-|%1|, |%2|, |%3|, ..., |%9|. This is to prevent horrendous crashes when
-type mismatches occur: using a pointer to a phrase when trying to print a
-source code reference, for instance.
-
 The texts to be substituted in place of |%1|, |%2|, ..., are called the
 "quotations". The value is either a range of words in the source text, or
-else a pointer to some data structure, depending on the type. The type is a
+else a pointer to some object, depending on the type. The type is a
 single character code. (This coding system is used only here, and could
 easily be changed, but there seems no reason to.)
 
-The type codes are S(ource), W(ords), B(inary predicate), E(xtension),
-(p)H(rase), I(nvocation), N(umber), O(bject), P(roperty name), T(ext),
-(t)Y(pe specification).

+Shared modules like this one are tweaked in behaviour by defining "callback
+functions". This means that the parent might provide a function of its own
+which would answer a question put to it by the module, or take some action
+on behalf of the module: it's a callback in the sense that the parent is
+normally calling the module, but then the module calls the parent back to

+
+@ |DESCRIBE_SOURCE_FILE_PROBLEMS_CALLBACK| can change the description of a
+file used in problem messages; Inform uses this to say "the source text" or
+"Standard Rules" rather than citing filenames. See //ProblemBuffer::copy_source_reference//.
+
+@ |DOCUMENTATION_REFERENCE_PROBLEMS_CALLBACK| is invited to add a clickable
+link to in-app documentation; if no callback function is provided, no
+such links appear. See //Problems::problem_documentation_links//.
+
+@ |ENDING_MESSAGE_PROBLEMS_CALLBACK| is called just before a problem message
+is about to end, and can be used to append some extra wording. See
+//Problems::issue_problem_end//.
+
+@ |FIRST_PROBLEMS_CALLBACK| is called before the first problem in a run is
+issued, and takes as an argument the |text_stream *| to which problems are
+being written. See //Problems::show_problem_location//.
+
+@ |GLOSS_EXTENSION_SOURCE_FILE_PROBLEMS_CALLBACK| is called to add a note
+like "in the extension Locksmith by Emily Short"; see //Problems::show_problem_location//.
+
+@ |INFORMATIONAL_ADDENDA_PROBLEMS_CALLBACK| is called just before a problems
+report closes, to give it a chance to add informational messages. (//core//
+uses this mechanism to append text such as "There were 3 rooms and 27 things.")
+Such addenda are not problems, and do not affect the program's exit code.
+See //ProblemBuffer::write_reports//.
+
+@ |START_PROBLEM_FILE_PROBLEMS_CALLBACK| is called when //problems// wants
+to open some kind of file for problem messages, with two arguments: the
+filename |F| and the stream |P| to open to it. If the callback function wants
+this to come to anything, it must perform the file-open, and write any header
+material it would like. See //StandardProblems::start_problems_report//.
+
+@ |WORDING_FOR_HEADING_NODE_PROBLEMS_CALLBACK| is called to ask what wording

-@h Fatal errors.
-These are problems which cause an immediate exit of the program as soon as
-they are issued, and are typically used for filing-system disasters or
-failed assertions (so-called "internal errors").
+@h The story of a non-fatal problem message.
+Suppose that the //core// module wants to issue a problem message: what
+happens?
+
+This depends on how complicated it is. The //problems// system has three
+levels:
+(3) //Problems, Level 3// contains functions for problem messages which have
+a commonly-needed shape to them: for example, //StandardProblems::sentence_problem//.
+The functions in question call down to...
+(2) //Problems, Level 2//, which contains functions to accept "quotations" and
+a problem message with placeholders in to hold those quotations; after which,
+they call down to...
+(1) //Problems, Level 1//, where the text of a message is stored in the
+"problem buffer" and eventually printed or written to a file.
+
+Most of the problems issued by Inform look like this:
+= (text as InC)
+	StandardProblems::sentence_problem(Task::syntax_tree(), _p_(PM_BadDesk),
+		"Inform does not support standing desks",
+		"and needs your laptop to be lower than your ribcage at all times.");
+=
+The sigil for this (hypothetical) problem message is |PM_BadDesk|, and note the
+use of the |_p_| macro to refer to it: see //Problems, Level 0// for more. The
+first piece of text is always produced, and the second added only on the first
+occurrence. //core// doesn't need to do anything more than make this one
+function call to Level 3, and //problems// does everything else.
+
+But a significant number of problems are less standard in shape and are
+called "handmade", meaning that //core// has to call some Level 2 functions.
+For example:
+= (text as InC)
+	Problems::quote_source(1, current_sentence);
+	Problems::quote_wording(2, W);
+	StandardProblems::handmade_problem(Task::syntax_tree(), _p_(PM_ScottishPlay));
+	Problems::issue_problem_segment(
+		"In the sentence %1, it looks as if '%2' might be a reference to a "
+		"theatrical work connected with Scotland.");
+	Problems::issue_problem_end();
+=
+What happens, in sequence, is that we
+(a) Establish what material should go into the placeholders |%1| and |%2|,
+(b) Call //StandardProblems::handmade_problem// to begin work,
+(c) Call //Problems::issue_problem_segment// a number of times -- though often
+just once -- to put some text into the problem, and
+(d) Call //Problems::issue_problem_end// to signal that we are done.
+
+@ As this demonstrates, problem messages are expanded from prototypes using
+a |printf|-like formatting system. Unlike |printf|, though, where |%s| means
+a string and |%d| a number, here the escape codes do not indicate the type of
+the data: they are simply |%1|, |%2|, |%3|, ..., |%9|. This is to prevent
+horrendous crashes when type mismatches occur: using a pointer to a phrase
+when trying to print a source code reference, for instance.
+
+The placeholders do not need to be used contiguously -- if you want to use
+just |%4| and |%7|, feel free.
+
+Four further escape codes switch between problem message versions, as follows:
+(*) |%L| means "long form", the version used the first time this message is
+generated,
+(*) |%S| means "short form", for subsequent times,
+(*) |%A| means "both long and short", which is the situation at the start,
+
+Note that the form is reset to |%A| when a new problem message begins, but not
+in between calls to //Problems::issue_problem_segment//: i.e., if one segment
+leaves things in |%L|, the next segment, if there is one, resumes that way.
+
+For example, |"You wrote %1: %Sagain, %2.%Lbut %2, %3"| is the message
+text used by //StandardProblems::sentence_problem//. 
+= (text)
+	                 "You wrote %1: %Sagain, %2.%Lbut %2, %3"
+	on first use --> "You wrote %1: but %2, %3"
+	subsequently --> "You wrote %1: again, %2."
+=
+Here the punctuation; |%3| is expected to end with a full stop and |%2| not to.
+
+Finally, the escape |%P| means "poragraph break here", and is used for adding
+subsequent clarifications to long or complicated problems.
+
+@ //Problems, Level 3// contains functions for standardly-shaped problems, then.
+A significant amount of this section also deals with internal errors, that is,
+failed assertions; while //foundation// provides the basic system for handling
+those -- i.e., print and then exit the program -- //core// redirects all
+internal errors to //StandardProblems::internal_error_fn//, which ensures that
+they pass through our problems machinery here, and are thus properly recorded
+in the HTML problems report in the Inform app (if that's what the user is
+using).
+
+@ //Problems, Level 2// contains functions for making quotations to fill the
+placeholders with content -- see //problem_quotation//.
+
+The mechanism for determining whether an explanation has been given before is
+//Problems::explained_before//. The obvious thing would be to go by the sigils
+of previously issued messages, but it actually uses the textual token supplied
+on the call to //Problems::issue_problem_begin//, which allows for some
+variations -- Level 3 functions are able to use this to ensure that particular
+kinds of message are always, or are never, explained.
+
+As Level 2 generates problem text, it calls down into //ProblemBuffer::output_problem_buffer//
+at Level 1.
+
+Just a few functions at Level 2 issue fatal errors -- that is, problems which
+cause an immediate exit of the program as soon as they are issued, and are
+typically used for filing-system disasters or failed assertions (so-called
+"internal errors").
 
 Facilities for these are very limited:
-(*) //Problems::Fatal::issue// for a simple message with fixed wording.
-(*) //Problems::Fatal::filename_related// for a message relating to a file.
+(*) //Problems::fatal// for a simple message with fixed wording.
+(*) //Problems::fatal_on_file// for a message relating to a file.
+
+These routines have to be written with care because a file-system disaster
+might mean that the problems file itself cannot be written to.
+
+@ //Problems, Level 1// is concerned with the "problem buffer" |PBUFF|.
+This is a text used to hold the problem message as it is assembled from pieces,
+and only Level 2 functions should print to it. Even they should call down to
+two Level 1 functions when they want to write something other than straightforward
+text:
+(*) Source text from the lexer can be quoted into it with //ProblemBuffer::copy_text//,
+which automatically trims excessive quotes for length.
+(*) References to positions in the source text can be inserted with
+//ProblemBuffer::copy_source_reference//: there is a sort of protocol for how
+this is done, with use of the magic |SOURCE_REF_CHAR| which will be
+intercepted later on when the problems file is written out as HTML (see
+//foundation: HTML// for details).
+
+@ When a portion of text has been buffered which Level 2 wants to get shot of,
+it calls down to //ProblemBuffer::output_problem_buffer// to send this to a
+file. By default, the text is actually sent three ways: to the standard
+console output, to the debugging log (if there is one), and to the telemetry
+file (if there is one). But this can be diverted with
+//ProblemBuffer::redirect_problem_stream//, telling it to send problem text
+just one way.
 
 @h Telemetry.
 The //Telemetry// system isn't really to do with problems, except that it
