NAME

       bg-installer - Standardized installer program.

SYNOPSIS

       bg-installer [top-directory] <LIST

DESCRIPTION

       The  program  bg-installer  reads  an installation instruction file from standard input, and executes the
       instructions in the directory named on the command line.

       Each line in the file is an individual instruction.   Blank  lines  and  lines  beginning  with  "#"  are
       ignored.   Lines  beginning with ">", if present, instruct bg-installer as to which base directory to use
       (see below).  All other lines must have following format:

              CMD:[OWNER]:[GROUP]:MODE:DIR[:FILENAME[:SOURCE]]

       CMD    is a single character specifying the installation command, optionally followed by  "?"  indicating
              the  command  should  only  execute if the source exists.  If the "?" is followed by a name, it is
              used instead of SOURCE as the filename to test.

       OWNER  (optional) is the owner user ID or name for the target file.

       GROUP  (optional) is the group ID or name for the target file.

       MODE   is the permissions of the installed file in octal.

       DIR    is the subdirectory of the installation prefix for the destination file.

       FILENAME
              (optional) is the name of the file  to  install  into  the  directory.   It  may  be  omitted  for
              directories.

       SOURCE (optional)  is the name of the source file to install, if it differs from the destination file, or
              the path in the symlink.

       If SOURCE contains wildcards, the command is repeated once for each matching filename.

       If FILENAME is empty, it is replaced with the value of SOURCE after wildcard expansion.  Each instance of
       "$N"  in FILENAME where "N" is a single digit is replaced with the Nth part of the source filename.  "$0"
       is replaced with the whole source filename.

       The target filename is "PREFIX/TOP/DIR/FILENAME" where "PREFIX" is the value of $install_prefix if it  is
       set, TOP is the directory given on the command line, and DIR and FILENAME given in the installation file.

       o      "c" lines copy regular files from the current directory

       o      "d" lines create directories

       o      "s" lines create symlinks (UID, GID, and MODE are ignored)

       o      "l" lines copy libraries using libtool

       When  bg-installer  encounters  a  base  directory directive, as indicated above, it opens the file named
       conf-BASE (where BASE is the word on the directive line), reads the first line, and uses that as the base
       directory (prefixed by $install_prefix as above).

OPTIONS

       -v, --verbose
              List the files as they are processed.

       -n, --dry-run
              Don't modify any files, just display.

       -c, --check
              Check destinations instead of installing.

       -h, --help
              Display usage information and exit.

EXAMPLES

              >bin
              c:::755::prog2
              c?:root:root:4750::prog2
              >include
              d:::755:package
              c:::644:package:base.h:pkgbase.h
              s:::::package.h:package/base.h

       This  reads conf-bin, and installs prog1 and setuid root prog2 (if it was built) under it.  It then reads
       conf-include, creates the directory package under it, and installs pkgbase.h as base.h in that directory.
       It also creates a symlink package.h to package/base.h.

ENVIRONMENT

       install_prefix
              If set, is prefixed to all destination file names.
