   5 ugrep: a sample program demonstrating the use of ICU regular expression API.
   6
   7 usage:   ugrep [options] pattern [file ...]
   8
   9    --help                 Output a brief help message
  10    -n,  --line-number     Prefix each line of output with the line number within its input file.
  11    -V,  --version         Output the program version number
  12
  13
  14 The program searches for the specified regular expression in each of the
  15 specified files, and outputs each matching line.
  16
  17 Input files are in the system default (locale dependent) encoding, unless they
  18 begin with a BOM, in which case they are assumed to be in the UTF encoding
  19 specified by the BOM.  Program output is always in the system's default
  20 8 bit code page.

  23 Files:
  24     ./ugrep.c                 source code for the sample
  25     ./ugrep.sln               Windows MSVC workspace.  Double-click this to get started.
  26     ./ugrep.vcproj            Windows MSVC project file.
  27     ./Makefile                Makefile for Unixes.  Needs gmake.

  30 To Build ugrep on Windows
  31     1.  Install and build ICU
  32     2.  In MSVC, open the workspace file icu\samples\ugrep\ugrep.sln
  33     3.  Choose a Debug or Release build.
  34     4.  Build.
  35
  36 To Run on Windows
  37     1.  Start a command shell window
  38     2.  Add ICU's bin directory to the path, e.g.
  39             set PATH=c:\icu\bin;%PATH%
  40         (Use the path to where ever ICU is on your system.)
  41     3.  cd into the ugrep directory, e.g.
  42             cd c:\icu\source\samples\ugrep\debug
  43     4.  Run it
  44             ugrep ...
  45
  46
  47 To Build on Unixes
  48     1.  Build ICU.  Specify an ICU install directory when running configure,
  49         using the --prefix option.  The steps to build ICU will look something
  50         like this:
  51            cd <icu directory>/source
  52            runConfigureICU <platform-name> --prefix <icu install directory> [other options]
  53            gmake all
  54
  55     2.  Install ICU,
  56            gmake install
  57
  58     3.  Build the sample
  59            Put the install directory containing icu-config on the $PATH.
  60                This will generally be <icu install directory>/bin
  61            cd <icu directory>/source/samples/ugrep
  62            gmake
  63
  64  To Run on Unixes
  65            cd <icu directory>/source/samples/ugrep
  66
  67            export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
  68            ugrep ...
  69
  70
  71  Note:  The name of the LD_LIBRARY_PATH variable is different on some systems.
  72         If in doubt, run the sample using "gmake check", and note the name of
  73         the variable that is used there.  LD_LIBRARY_PATH is the correct name
  74         for Linux and Solaris.
