+.SH NAME
+lzgrep \- search LZMA compressed files for a regular expression
+.SH SYNOPSIS

+.RB  [ \-e ]
+.I pattern
+.IR filename ".\|.\|."
+.br
+.B lzegrep
+.RB ...
+.br
+.B lzfgrep
+.RB ...
+.SH DESCRIPTION
+.B  lzgrep
+is used to invoke the
+.BR grep (1)
+on LZMA compressed files. All options specified are passed directly to
+.BR 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
+.BR grep .
+.PP
+If
+.B lzgrep
+is invoked as
+.B lzegrep
+or
+.B lzfgrep
+then
+.B egrep
+or
+.B fgrep
+is used instead of
+.B grep.
+If the GREP environment variable is set,
+.B lzgrep
+uses it as the
+.B grep
+program to be invoked. For example:
+
+    for sh:  GREP=fgrep  lzgrep string files
+    for csh: (setenv GREP fgrep; lzgrep string files)

+.TH LZMORE 1 "30 Jun 2005" "LZMA utils"
+.SH NAME
+lzmore, lzless \- view LZMA compressed (text) files
+.SH SYNOPSIS
+.B lzmore
+.RI [ "filename ..."  ]
+.br
+.B lzless
+.RI [ "filename ..."  ]
+.SH DESCRIPTION
+.B  lzmore
+is a filter which allows examination of LZMA compressed text files
+one screenful at a time on a soft-copy terminal.
+.PP
+To use a pager other than the default
+.B more,
+set environment variable
+.B PAGER
+to the name of the desired program, such as
+.BR less .
+If
+.B lzmore
+is called as
+.B lzless
+then
+.B less
+is used as the
+.BR PAGER .
+.TP
+.BR e " or " q
+When the prompt --More--(Next file: 
+.IR file )
+is printed, this command causes lzmore to exit.
+.TP
+.B s
+When the prompt --More--(Next file: 
+.IR file )
+is printed, this command causes zmore to skip the next file and continue.
+.PP
+For list of keyboard commands supported while actually viewing the
+content of a file, refer to manual of the pager you use, usually
+.BR more (1)
+or
+.BR less (1). 
+.SH AUTHORS
+This manual page was ripped from
