Summary: How to write and maintain large Fortran code
Review: Fortran is still widely used in science and engineering, though if you look at new computer books, you can scarcely tell this. Since those usually discuss languages like C, C++ and Java. But when it comes to raw number crunching, and where a GUI might be nice, but is strictly secondary, there is a ton of legacy code in Fortran. So there is still a need for a book like this, which discusses how to use the latest version, Fortran 95. What the author strives for is to cover something lacking in many older Fortran texts. Those tend to explain the syntax and how to write small programs, of a few thousand lines or less. But there is often little discussion on how to manage the complexity of libraries stretching to 10^5 lines or 10^6 lines of code. How can you maintain and understand and add to these bodies? Issues like unit testing, which quite often discussed in java or C++, are well described here. Design discipline is also emphasised. So if you are still writing in Fortran, and are wondering about coping with growing code, consider this book.
