...mgrep is not a grep replacement, but it is intended to be grep-compatible: implemented options and behavior should be the same as those of grep.
mgrep is written in C++ using the Boost.Regex library.
A configure/make system is provided for Linux, but its sourcecode should compile on all platforms that have the std and Boost.Regex libraries installed.
SourceGlob is a Win32 tool for code search and visual display with code highlighting - like a visual grep tool. Windows Shell integration for fast access is provided. The current relaease is dedicated as preview.
