HOWTO: grep
Description: Print lines matching a pattern
Click here for ChangeLog
NOTE: I use GNU tar >= 1.13.25 so it's -j for .tar.bz2 files,
it's safe to assume that make, gcc, binutils, fileutils/coreutils, gawk, sed, and grep are prerequisites for almost everything

# GNU grep 2.5.4
# ==============
# Slackware 11.0, 12.0, 12.1: grep 2.5
# Slackware 12.2: grep 2.5.3

# Prerequisites:
# iconv
# bison
# PCRE

# If ftp.gnu.org is busy, use ibiblio instead
