It was originally developed to speed up verifying the integrity of tablespace files after power outages but can also be used after file copies\&. Because checksum mismatches will cause

+.SH "DESCRIPTION"
+.PP
+This script is used on Windows after building a MySQL distribution from source to create executable programs\&. It packages the binaries and support files into a Zip archive that can be unpacked at the location where you want to install MySQL\&.
+.PP
+\fBmake_win_bin_dist\fR
+is a shell script, so you must have Cygwin installed to use it\&.
+.PP
+This program\'s use is subject to change\&. Currently, you invoke it as follows from the root directory of your source distribution:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBmake_win_bin_dist [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIpackage_basename\fR\fR\fB [\fR\fB\fIcopy_def\fR\fR\fB \&.\&.\&.]\fR
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+The
+\fIpackage_basename\fR
+argument provides the basename for the resulting Zip archive\&. This name will be the name of the directory that results from unpacking the archive\&.
+.PP
+Because you might want to include files of directories from other builds, you can instruct this script to copy them in for you, using
+\fIcopy_def\fR
+arguments, which have the form
+\fIrelative_dest_name\fR=\fIsource_name\fR\&.
+.PP
+Example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+bin/mysqld\-max\&.exe=\&.\&./my\-max\-build/sql/release/mysqld\&.exe
+.fi
+.if n \{\

+.SH "DESCRIPTION"
+.PP
+Initially, the MySQL C API was developed to be very similar to that for the mSQL database system\&. Because of this, mSQL programs often can be converted relatively easily for use with MySQL by changing the names of the C API functions\&.
+.PP
+The
+\fBmsql2mysql\fR
+utility performs the conversion of mSQL C API function calls to their MySQL equivalents\&.
+\fBmsql2mysql\fR
+converts the input file in place, so make a copy of the original before converting it\&. For example, use
+\fBmsql2mysql\fR
+like this:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBcp client\-prog\&.c client\-prog\&.c\&.orig\fR
+shell> \fBmsql2mysql client\-prog\&.c\fR
+client\-prog\&.c converted
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+Then examine
+client\-prog\&.c
+and make any post\-conversion revisions that may be necessary\&.
+.PP
+\fBmsql2mysql\fR
+uses the
+\fBreplace\fR
+utility to make the function name substitutions\&. See
+\fBreplace\fR(1)\&.

+.SH "DESCRIPTION"
+.PP
+\fBmyisam_ftdump\fR
+displays information about
+FULLTEXT
+indexes in
+MyISAM
+tables\&. It reads the
+MyISAM
+index file directly, so it must be run on the server host where the table is located\&. Before using
+\fBmyisam_ftdump\fR, be sure to issue a
+FLUSH TABLES
+statement first if the server is running\&.
+.PP
+\fBmyisam_ftdump\fR
+scans and dumps the entire index, which is not particularly fast\&. On the other hand, the distribution of words changes infrequently, so it need not be run often\&.
+.PP
+Invoke
+\fBmyisam_ftdump\fR
+like this:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBmyisam_ftdump [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fItbl_name\fR\fR\fB \fR\fB\fIindex_num\fR\fR
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+The
+\fItbl_name\fR
+argument should be the name of a
+MyISAM
+table\&. You can also specify a table by naming its index file (the file with the
+\&.MYI
+suffix)\&. If you do not invoke
+\fBmyisam_ftdump\fR
+in the directory where the table files are located, the table or index file name must be preceded by the path name to the table\'s database directory\&. Index numbers begin with 0\&.
+.PP
+Example: Suppose that the
+test
+database contains a table named
+mytexttablel
+that has the following definition:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+CREATE TABLE mytexttable
+(
+  id   INT NOT NULL,
+  txt  TEXT NOT NULL,
+  PRIMARY KEY (id),
+  FULLTEXT (txt)
+) ENGINE=MyISAM;
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+The index on
+id
+is index 0 and the
+FULLTEXT
+index on
+txt
+is index 1\&. If your working directory is the
+test
+database directory, invoke
+\fBmyisam_ftdump\fR
+as follows:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBmyisam_ftdump mytexttable 1\fR
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+If the path name to the
+test
+database directory is
+/usr/local/mysql/data/test, you can also specify the table name argument using that path name\&. This is useful if you do not invoke
+\fBmyisam_ftdump\fR
+in the database directory:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBmyisam_ftdump /usr/local/mysql/data/test/mytexttable 1\fR
+.fi
+.if n \{\

+\fBmyisamchk\fR

+\fBmyisamchk\fR

+.PP
+\fItbl_name\fR
+is the database table you want to check or repair\&. If you run
+\fBmyisamchk\fR
+somewhere other than in the database directory, you must specify the path to the database directory, because
+\fBmyisamchk\fR
+has no idea where the database is located\&. In fact,
+\fBmyisamchk\fR
+does not actually care whether the files you are working on are located in a database directory\&. You can copy the files that correspond to a database table into some other location and perform recovery operations on them there\&.
+.PP
+You can name several tables on the
+\fBmyisamchk\fR
+command line if you wish\&. You can also specify a table by naming its index file (the file with the
+\&.MYI
+suffix)\&. This enables you to specify all tables in a directory by using the pattern
+*\&.MYI\&. For example, if you are in a database directory, you can check all the

+.PP
+If you use
+\fBmyisamchk\fR

+FULLTEXT

+.PP
+The problem occurs because these parameters are known only by the server\&. They are not stored in
+MyISAM

+ft_min_word_len,
+ft_max_word_len, and
+ft_stopword_file
+values to
+\fBmyisamchk\fR

+.SH "DESCRIPTION"
+.PP
+The
+\fBmyisampack\fR
+utility compresses
+MyISAM
+tables\&.
+\fBmyisampack\fR
+works by compressing each column in the table separately\&. Usually,
+\fBmyisampack\fR
+packs the data file 40% to 70%\&.
+.PP
+When the table is used later, the server reads into memory the information needed to decompress columns\&. This results in much better performance when accessing individual rows, because you only have to uncompress exactly one row\&.
+.PP
+MySQL uses
+mmap()
+when possible to perform memory mapping on compressed tables\&. If
+mmap()
+does not work, MySQL falls back to normal read/write file operations\&.
+.PP
+Please note the following:

+If the
+\fBmysqld\fR
+server was invoked with external locking disabled, it is not a good idea to invoke
+\fBmyisampack\fR
+if the table might be updated by the server during the packing process\&. It is safest to compress tables with the server stopped\&.

+Each file name argument should be the name of an index (\&.MYI) file\&. If you are not in the database directory, you should specify the path name to the file\&. It is permissible to omit the

+.PP
+After you compress a table with
