Found from http://www.tldp.org/LDP/abs/html/spe...rs.html#BGLOOP

Quoting word-to-word from the above url.

Code:
redirection from/to stdin or stdout [dash].

(cd /source/directory && tar cf - . ) | (cd /dest/directory && tar xpvf -)
# Move entire file tree from one directory to another
# [courtesy Alan Cox <a.cox@swansea.ac.uk>, with a minor change]

# 1) cd /source/directory    Source directory, where the files to be moved are.
# 2) &&                     "And-list": if the 'cd' operation successful, then execute the next command.
# 3) tar cf - .              The 'c' option 'tar' archiving command creates a new archive,
#                            the 'f' (file) option, followed by '-' designates the target file as stdout,
#                            and do it in current directory tree ('.').
# 4) |                       Piped to...
# 5) ( ... )                 a subshell
# 6) cd /dest/directory      Change to the destination directory.
# 7) &&                     "And-list", as above
# 8) tar xpvf -              Unarchive ('x'), preserve ownership and file permissions ('p'),
#                            and send verbose messages to stdout ('v'),
#                            reading data from stdin ('f' followed by '-').
#
#                            Note that 'x' is a command, and 'p', 'v', 'f' are options.
# Whew!



# More elegant than, but equivalent to:
#   cd source/directory
#   tar cf - . | (cd ../dest/directory; tar xpvf -)
#
# cp -a /source/directory /dest/directory     also has same effect.

icmstart.rc

icmstart.rc(7)						      icmstart resource file						    icmstart.rc(7)

NAME

       icmstart.rc - The icmstart(1) resource file

DESCRIPTION

       The icmstart.rc file defines the initial files of a program that are installed by icmstart(1).

       By  default  icmstart.rc is found in /etc/icmake/icmstart.rc, but if a file $HOME/.icmake/icmstart.rc is found then the latter file is used
       by icmstart(1). $HOME/.icmake/icmstart.rc in turn is overruled by specifying a -c option when invoking icmstart(1).

       The default resource file contains the following specifications, preparing for the construction of a C++ program using icmbuild(1):

	   CLASSES
	   P main.cc
	   P main.ih
	   P usage.cc
	   P version.cc
	   P ? scanner
	   P ? parser

       The icmstart.rc file may contain:

       o      empty lines, which are ignored;

       o      lines beginning with a hash-character (#), also ignored;

       o      Optionally: a P (don't install with icmstart xxx library) or an L (don't install with icmstart xxx program), followed  by  a  blank;
	      see also icmstart(1).

       o      Optionall:  a  ? (followed by a blank) following the optional P or L in which case the installation of the element must be confirmed
	      by the user.

       o      Source path names. Relative path names are interpreted relative to the current working  directory.  Environment  variables  are  not
	      expanded, the initial tilde character is interpreset as the user's home directory.

       o      Source  path  names followed by a destination (relative to the directory initialized by icmstart(1)).  A source path may be either a
	      file or a directory. If a directory is specified then all files in and below that directory will be installed.

       When specifying a destination a path may be specified as well. However, the destination path is always interpreted relative to the  instal-
       lation directory specified when calling icmstart(1).

       If a destination is omitted, the source is installed as specified below icmstart(1)'s destination directory.

EXAMPLES

       The following entries can be used in an icmstart.rc file:

       o      source
	      `Source'	must be in the skeleton directory visited by icmstart(1) and is installed as source in the destination directory specified
	      when calling icmstart(1).

       o      source dest
	      `Source' must be in the skeleton directory visited by icmstart(1) and is installed as dest in the  destination  directory  specified
	      when calling icmstart(1).

       o      ~/path
	      `~/path'	is installed as ~/path in the destination directory specified when calling icmstart(1). The ~-character is expanded to the
	      user's home directory.

       o      ~/path dest
	      `~/path' is installed as dest in the destination directory specified when calling icmstart(1). The  ~-characteris  expanded  to  the
	      user's home directory.

       o      /path
	      `/path' is installed as ./path in the destination directory specified when calling icmstart(1).

       o      /path dest
	      `/path' is installed as dest in the destination directory

       o      ? source
	      The user must confirm the installation of source.

       o      ? source dest
	      The user must confirm the installation of source as dest in the destination directory specified when calling icmstart(1).

       o      # text
	      Interpreted as comment and ignored. The #-character must be the first character on the line.

       o      an empty line
	      Empty lines are skipped.

FILES

       The mentioned paths are sugestive only and may be installation dependent:

       o      /usr/share/icmake/icmconf Example of an icmbuild configuration file;

       o      /usr/share/icmake/CLASSES Example of an icmbuild CLASSES file.

       o      /usr/share/icmake/icmstart.rc Default skeleton resource file.
