+=head1 DESCRIPTION
+
+mysql_tableinfo asks a MySQL server information about its
+databases, tables, table columns and index, and stores this
+in tables called `db`, `tbl` (or `tbl_status`), `col`, `idx` 
+(with an optional prefix specified with --prefix).
+After that, you can query these information tables, for example
+to build your admin scripts with SQL queries, like
+
+SELECT CONCAT("CHECK TABLE ",`database`,".",`table`," EXTENDED;") 
+FROM info.tbl WHERE ... ;
+
+as people usually do with some other RDBMS
+(note: to increase the speed of your queries on the info tables,
+you may add some index on them).
+
+The database_like_wild and table_like_wild instructs the program
+to gather information only about databases and tables
+whose names match these patterns. If the info
+tables already exist, their rows matching the patterns are simply
+deleted and replaced by the new ones. That is,
+old rows not matching the patterns are not touched.
+If the database_like_wild and table_like_wild arguments
+are not specified on the command-line they default to "%".
+
+The program :
+
+- does CREATE DATABASE IF NOT EXISTS database_to_write
+where database_to_write is the database name specified on the command-line.
+
+- does CREATE TABLE IF NOT EXISTS database_to_write.`db`
+
+- fills database_to_write.`db` with the output of
+SHOW DATABASES LIKE database_like_wild
+
+- does CREATE TABLE IF NOT EXISTS database_to_write.`tbl`
+(respectively database_to_write.`tbl_status`
+if the --tbl-status option is on)
+
+- for every found database,
+fills database_to_write.`tbl` (respectively database_to_write.`tbl_status`)
+with the output of 
+SHOW TABLES FROM found_db LIKE table_like_wild
+(respectively SHOW TABLE STATUS FROM found_db LIKE table_like_wild)
+
+- if the --col option is on,
+    * does CREATE TABLE IF NOT EXISTS database_to_write.`col`
+    * for every found table,
+      fills database_to_write.`col` with the output of 
+      SHOW COLUMNS FROM found_tbl FROM found_db
+
+- if the --idx option is on,
+    * does CREATE TABLE IF NOT EXISTS database_to_write.`idx`
+    * for every found table,
+      fills database_to_write.`idx` with the output of 
+      SHOW INDEX FROM found_tbl FROM found_db
+
+Some options may modify this general scheme (see below).
+
+As mentioned, the contents of the info tables are the output of
+SHOW commands. In fact the contents are slightly more complete :
+
+- the `tbl` (or `tbl_status`) info table 
+  has an extra column which contains the database name,
+
+- the `col` info table
+  has an extra column which contains the table name,
+  and an extra column which contains, for each described column,
+  the number of this column in the table owning it (this extra column
+  is called `Seq_in_table`). `Seq_in_table` makes it possible for you
+  to retrieve your columns in sorted order, when you are querying
+  the `col` table. 
+
+- the `index` info table
+  has an extra column which contains the database name.
+
+Caution: info tables contain certain columns (e.g.
+Database, Table, Null...) whose names, as they are MySQL reserved words,
+need to be backquoted (`...`) when used in SQL statements.
+
+=head1 OPTIONS
+
+=over 4
+
+=item --clear
+
+Does DROP TABLE on the info tables (only those that the program is
+going to fill, for example if you do not use --col it won't drop
+the `col` table) and processes normally. Does not drop database_to_write.
+
+=item --clear-only
+
+Same as --clear but exits after the DROPs.
+
+=item --col
+
+Adds columns information (into table `col`).
+
+=item --idx
+
+Adds index information (into table `idx`).
+
+=item --prefix prefix
+
+The info tables are named from the concatenation of prefix and,
+respectively, db, tbl (or tbl_status), col, idx. Do not quote ('')
+or backquote (``) prefix.
+
+=item -q, --quiet
+
+Does not warn you about what the script is going to do (DROP TABLE etc)
+and does not ask for a confirmation before starting.
+
+=item --tbl-status
+
+Instead of using SHOW TABLES, uses SHOW TABLE STATUS
+(much more complete information, but slower). 
+
+=item --help
+
+Display helpscreen and exit
+
+=item -u, --user=#         
+
+user for database login if not current user. Give a user
+who has sufficient privileges (CREATE, ...).
+
+=item -p, --password=#     
+
+password to use when connecting to server
+
+=item -h, --host=#     
+
+host to connect to
+
+=item -P, --port=#         
+
+port to use when connecting to server
+
+=item -S, --socket=#         
+
+UNIX domain socket to use when connecting to server
+

+that it does the right thing for you.

+Patches adding bug fixes, documentation and new features are welcome.
+
+=head1 TO DO
+
+Use extended inserts to be faster (for servers with many databases
+or tables). But to do that, must care about net-buffer-length.
