#  Make rules for installing scripts and script-modules. 
#
#  This file is intended for use in Makefile via the include directive, e.g.
#
#      include $(BUILD_DIR)/script_rules.mk
#
#  It is assumed that the environment has been set by sourcing the build
#  resource file (buildrc).
# 
#  This file defines the following rules for library modules:
#
#      all, lib, archive, linked_lib, utest, exe, clean, clean_lib, clean_exe,
#      clean_depend, depend.

#
#  RULES for installing scripts and script modules 
#
#    EXE_SRC specifies a list of files that contain executable scripts.
#    Each file in the list will be installed in the $(BIN_DEST) directory
#    and will be given executable permissions.  If the variable EXE_EXT is
#    set, this extension will be stripped from the end of the source file
#    when it is installed, e.g. if EXE_SRC = "foo.pl" and EXE_EXT = ".pl",
#    the executable installed in BIN_DEST will be named "foo". 
#
#    Installation of library modules works in a similiar fashion, with the
#    variables MOD_SRC and MOD_EXT taking the place of EXE_SRC and EXE_EXT.
#    In addition, the Makefile *MUST* specify a destination directory for
#    installation.  Typically, this is set to a subdirectory of BASE_DIR,
#    e.g. MOD_DEST = $(BASE_DIR)/perllib for perl modules. 
#
#    The EXE_SRC variable only needs to be set executable scripts need to be
#    built.  Likewise MOD_SRC determines if script modules should be built.
#    The logic to set "src" to "invalid" is used to prevent shell errors
#    if either or both of these variables are not set. 
#
#    However, if MOD_SRC is set, MOD_DEST must also be set to the location
#    of a valid directory.  The same is also true for EXE_SRC and BIN_DEST,
#    but BIN_DEST is properly set when the buildrc resource file is sourced.
