Linux Programming Tools Unveiled

In the recent years, Linux, a public domain, freely available Unix variant has attracted the people very much. Today’s complex production environments demands superior application performance. Linux is having extraordinary advantages such as : complete source code access, availability of exceptional optimization, testing tools. This book is to explore this facet of Linux.
