/*
** INSTRUCTIONS
**
** This module exports a single tcl command - [register_tcl_module]. When
** invoked, it registers a special virtual table module with a database
** connection.
**
** The virtual table is currently read-only. And always returns zero rows.
** It is created with a single argument - the name of a Tcl command - as
** follows:
**
**   CREATE VIRTUAL TABLE x1 USING tcl(tcl_command);
**
** The command [tcl_command] is invoked when the table is first created (or
** connected), when the xBestIndex() method is invoked and when the xFilter()
** method is called. When it is created (or connected), it is invoked as
** follows:
**
**   tcl_command xConnect
**
** In this case the return value of the script is passed to the
** sqlite3_declare_vtab() function to create the virtual table schema.
**
** When the xBestIndex() method is called by SQLite, the Tcl command is
** invoked as:
**
**   tcl_command xBestIndex CONSTRAINTS ORDERBY MASK
**
** where CONSTRAINTS is a tcl representation of the aConstraints[] array,
** ORDERBY is a representation of the contents of the aOrderBy[] array and
** MASK is a copy of sqlite3_index_info.colUsed. For example if the virtual
** table is declared as:
**
**   CREATE TABLE x1(a, b, c)
**
** and the query is:
**
**   SELECT * FROM x1 WHERE a=? AND c<? ORDER BY b, c;
**
** then the Tcl command is:
**
**   tcl_command xBestIndex                                  \
**     {{op eq column 0 usable 1} {op lt column 2 usable 1}} \
**     {{column 1 desc 0} {column 2 desc 0}}                 \
**     7
**
** The return value of the script is a list of key-value pairs used to
** populate the output fields of the sqlite3_index_info structure. Possible
** keys and the usage of the accompanying values are:
** 
**   "orderby"          (value of orderByConsumed flag)
**   "cost"             (value of estimatedCost field)
**   "rows"             (value of estimatedRows field)
**   "use"              (index of used constraint in aConstraint[])
**   "omit"             (like "use", but also sets omit flag)
**   "idxnum"           (value of idxNum field)
**   "idxstr"           (value of idxStr field)
**
** Refer to code below for further details.
**
** When SQLite calls the xFilter() method, this module invokes the following
** Tcl script:
**
**   tcl_command xFilter IDXNUM IDXSTR ARGLIST
**
** IDXNUM and IDXSTR are the values of the idxNum and idxStr parameters
** passed to xFilter. ARGLIST is a Tcl list containing each of the arguments
** passed to xFilter in text form.
**
** As with xBestIndex(), the return value of the script is interpreted as a
** list of key-value pairs. There is currently only one key defined - "sql".
** The value must be the full text of an SQL statement that returns the data
** for the current scan. The leftmost column returned by the SELECT is assumed
** to contain the rowid. Other columns must follow, in order from left to
** right.
