-** SUMMARY
-**
-**   This file implements the 'io' subcommand of the test program. It is used
-**   for testing the performance of various combinations of write() and fsync()
-**   system calls. All operations occur on a single file, which may or may not
-**   exist when a test is started.
-**
-**   A test consists of a series of commands. Each command is either a write
-**   or an fsync. A write is specified as "<amount>@<offset>", where <amount>
-**   is the amount of data written, and <offset> is the offset of the file
-**   to write to. An <amount> or an <offset> is specified as an integer number
-**   of bytes. Or, if postfixed with a "K", "M" or "G", an integer number of
-**   KB, MB or GB, respectively. An fsync is simply "S". All commands are
-**   case-insensitive.
-**
-**   Example test program:
-**
-**        2M@6M 1492K@4M S 4096@4K S
-**
-**   This program writes 2 MB of data starting at the offset 6MB offset of
-**   the file, followed by 1492 KB of data written at the 4MB offset of the
-**   file, followed by a call to fsync(), a write of 4KB of data at byte
-**   offset 4096, and finally another call to fsync().
-**
-**   Commands may either be specified on the command line (one command per
-**   command line argument) or read from stdin. Commands read from stdin
-**   must be separated by white-space.
-**
-** COMMAND LINE INVOCATION
-**
-**   The sub-command implemented in this file must be invoked with at least
-**   two arguments - the path to the file to write to and the page-size to
-**   use for writing. If there are more than two arguments, then each
-**   subsequent argument is assumed to be a test command. If there are exactly
-**   two arguments, the test commands are read from stdin.
-**
-**   A write command does not result in a single call to system call write().
-**   Instead, the specified region is written sequentially using one or
-**   more calls to write(), each of which writes not more than one page of
-**   data. For example, if the page-size is 4KB, the command "2M@6M" results
-**   in 512 calls to write(), each of which writes 4KB of data.
-**
-** EXAMPLES
-**
-**   Two equivalent examples:
-**
-**     $ lsmtest io testfile.db 4KB 2M@6M 1492K@4M S 4096@4K S
-**     3544K written in 129 ms
-**     $ echo "2M@6M 1492K@4M S 4096@4K S" | lsmtest io testfile.db 4096 
-**     3544K written in 127 ms
