+.SH DESCRIPTION
+.IR  Bzgrep
+is used to invoke the
+.I grep
+on bzip2-compressed files. All options specified are passed directly to
+.I grep.
+If no file is specified, then the standard input is decompressed
+if necessary and fed to grep.
+Otherwise the given files are uncompressed if necessary and fed to
+.I grep.
+.PP
+If
+.I bzgrep
+is invoked as
+.I bzegrep
+or
+.I bzfgrep
+then
+.I egrep
+or
+.I fgrep
+is used instead of
+.I grep.
+If the GREP environment variable is set,
+.I bzgrep
+uses it as the
+.I grep
+program to be invoked. For example:
+
+    for sh:  GREP=fgrep  bzgrep string files
+    for csh: (setenv GREP fgrep; bzgrep string files)
