The shell script wgetrel intelligently transverses the Internet
searching for web pages by determining the relevance of HTML documents
to a search criteria. The criteria is specified by boolean
operators-the supported operators are logical or, logical and, and
logical not. These operators are represented by the symbols, "|",
"&", and, "!", respectively, and left and right parenthesis, "(" and
")", are used as grouping operators. The relevance of the documents is
determined by the program htmlrel, which is a modification to the
program rel(1). Source modifications are provided in the wgetrel
distribution. Also required is Hrvoje Niksic's excellent program,
wget(1). The shell script, wgetrel, can reduce web searching by about
an order of magnitude.
