`About the Author
`A professional writer for more than six years, Martin C. Brown (MC) is the author of both the
`Perl and Python Annotated Archives and Complete Reference books (all four Osborne/McGraw-
`Hill), Microsoft IIS 6 Delta Guide (Sams Publishing), and 14 other published computing titles.
`His expertise spans myriad development languages and platforms—Perl, Python, Java,
`JavaScript, Basic, Pascal, Modula-2, C, C++, Rebol, Gawk, Shellscript, Windows, Solaris,
`Linux, BeOS, Microsoft WP, Mac OS, and more—as well as web programming, systems
`management, and integration. MC is a regular contributor to ServerWatch.com and IBM
`developerWorks.
`He is also a regular writer of white papers and how-to guides for Microsoft on subjects such as
`migrating Solaris/Unix/Linux development and systems administration to Windows 2000 and
`2003 Server product lines. He draws on a rich and varied background as a founding member of
`a leading U.K. ISP, systems manager and IT consultant for an advertising agency and Internet
`solutions group, technical specialist for an intercontinental ISP network, and database designer
`and programmer—and as a self-confessed compulsive consumer of computing hardware and
`software. In his formative pre-writing life, he spent 10 years designing and managing mixed
`platform environments. As a result he has developed a rare talent of being able to convey the
`benefits and intricacies of his subject with equal measures of enthusiasm, professionalism, in-
`depth knowledge, and insight. MC is currently a member of the MySQL Documentation
`Team.
