# INSTRUCTIONS
#
# The following commands are available:
#
#   fts3_build_db_1 N
#     Using database handle [db] create an FTS4 table named t1 and populate
#     it with N rows of data. N must be less than 10,000. Refer to the
#     header comments above the proc implementation below for details.
#
#   fts3_build_db_2 N
#     Using database handle [db] create an FTS4 table named t2 and populate
#     it with N rows of data. N must be less than 100,000. Refer to the
#     header comments above the proc implementation below for details.
#
#   fts3_integrity_check TBL
#     TBL must be an FTS table in the database currently opened by handle
#     [db]. This proc loads and tokenizes all documents within the table,
#     then checks that the current contents of the FTS index matches the
#     results.

#     Todo.
