+A <dfn>regular expression</dfn> is a pattern that describes a set of strings. 
+Regular expressions are constructed analogously to arithmetic expressions,
+by using various operators to combine smaller expressions. 
+<samp><span class="command">grep</span></samp> understands
+two different versions of regular expression syntax:
+&ldquo;basic&rdquo;(BRE) and &ldquo;extended&rdquo;(ERE). 
+In <span class="sc">gnu</span> <samp><span class="command">grep</span></samp>,
+there is no difference in available functionality using either syntax. 
+In other implementations, basic regular expressions are less powerful. 
+The following description applies to extended regular expressions;
+differences for basic regular expressions are summarized afterwards.
