i'm glad to announce LikeGrep now suppots many threads (as many, as you want).
It gives you a chance to use all your CPU, wich are currently available in your personal PC.
For example, this version is 4 times faster, then previous version 2.9x
There are two ways to use this tool.
First, you can use it instead of standart UNIX grep as well (but it much faster, then grep)
Second, you can simple get the right Regular Expression without using read/parse file, tool shows you the Regular Expression, that it has built
