# Flawfinder.
# Released under the General Public License (GPL) version 2 or later.
# (C) 2001-2017 David A. Wheeler.

# To change version number, edit this here, the beginning of the
# "flawfinder" script, flawfinder.spec, setup.py, and index.html.
# Then "make test-is-correct" to get the updated version number.
# To distribute, "make distribute && su && make rpm".
# Then use make my_install to install to website image.
# Eventually switch to using DistUtils to autogenerate.

# Flawfinder has traditionally used INSTALL_DIR, INSTALL_DIR_BIN, and
# INSTALL_DIR_MAN.  Here we add support for GNU variables like prefix, etc.;
# users who override the older flawfinder-specific variable names will
# not notice any changes.  We define exec_prefix oddly so we can
# quietly merge these 2 systems:

prefix=/usr/local
INSTALL_DIR=$(prefix)
exec_prefix=$(INSTALL_DIR)
bindir=$(exec_prefix)/bin
INSTALL_DIR_BIN=$(bindir)

datarootdir=$(INSTALL_DIR)/share
mandir=$(datarootdir)/man
man1dir=$(mandir)/man1
INSTALL_DIR_MAN=$(man1dir)

# This installer doesn't install the compiled Python bytecode.
# It doesn't take long to compile the short Python code, so
# it doesn't save much time, and having the source code available
# makes it easier to see what it does.  It also avoids the
# (admittedly rare) problem of bad date/timestamps causing the
# compiled code to override later uncompiled Python code.
