-# te_* commands:
-#
-#
-#   te_read_sql DB SELECT-STATEMENT
-#   te_read_tbl DB TABLENAME
-#
-# These two commands are used to read a dataset from the database. A dataset
-# consists of N rows of M named columns of values each, where each value has a
-# type (null, integer, real, text or blob) and a value within the types domain.
-# The tcl format for a "dataset" is a list of two elements:
-#
-#   * A list of the column names.
-#   * A list of data rows. Each row is itself a list, where each element is
-#     the contents of a column of the row. Each of these is a list of two
-#     elements, the type name and the actual value.
-#
-# For example, the contents of table [t1] as a dataset is:
-#
-#   CREATE TABLE t1(a, b);
-#   INSERT INTO t1 VALUES('abc', NULL);
-#   INSERT INTO t1 VALUES(43.1, 22);
-#
-#   {a b} {{{TEXT abc} {NULL {}}} {{REAL 43.1} {INTEGER 22}}}
-#
-# The [te_read_tbl] command returns a dataset read from a table. The
-# [te_read_sql] returns the dataset that results from executing a SELECT
-# command.
-#
-#
-#   te_tbljoin ?SWITCHES? LHS-TABLE RHS-TABLE
-#   te_join ?SWITCHES? LHS-DATASET RHS-DATASET
-#
-# This command joins the two datasets and returns the resulting dataset. If 
-# there are no switches specified, then the results is the cartesian product
-# of the two inputs.  The [te_tbljoin] command reads the left and right-hand
-# datasets from the specified tables. The [te_join] command is passed the
-# datasets directly.
-#
-# Optional switches are as follows:
-#
-#   -on SCRIPT
-#   -using COLUMN-LIST
-#   -left
-#
-# The -on option specifies a tcl script that is executed for each row in the
-# cartesian product of the two datasets. The script has 4 arguments appended
-# to it, in the following order:
-#
-#   * The list of column-names from the left-hand dataset.
-#   * A single row from the left-hand dataset (one "data row" list as 
-#     described above.
-#   * The list of column-names from the right-hand dataset.
-#   * A single row from the right-hand dataset.
-#
-# The script must return a boolean value - true if the combination of rows
-# should be included in the output dataset, or false otherwise.
-#
-# The -using option specifies a list of the columns from the right-hand
-# dataset that should be omitted from the output dataset.
-#
-# If the -left option is present, the join is done LEFT JOIN style. 
-# Specifically, an extra row is inserted if after the -on script is run there
-# exist rows in the left-hand dataset that have no corresponding rows in
-# the output. See the implementation for more specific comments.
-#
-#
-#   te_equals ?SWITCHES? COLNAME1 COLNAME2 <-on script args>
-#
-# The only supported switch is "-nocase". If it is present, then text values
-# are compared in a case-independent fashion. Otherwise, they are compared
-# as if using the SQLite BINARY collation sequence.
