+# Makefile for Independent JPEG Group's software
+
+# This makefile is suitable for Unix-like systems.
+
+# See README and edit jconfig.h before saying "make" !!
+
+# Comment out this line if you don't have gcc:
+CC=gcc
+
+# You may need to adjust these cc options:
+CFLAGS= -O -g -Wall -DHAVE_GETOPT -DMEM_STATS
+LDFLAGS= -g
+# In particular:
+#   Remove -g and -Wall if not using gcc.
+#   Add -DBSD if on a pure BSD system (see jinclude.h).
+#   Remove -DHAVE_GETOPT if you don't have getopt(3) (see jcmain.c, jdmain.c).
+#   -DMEM_STATS is optional -- it enables gathering of memory usage statistics.
+#   You may also want to add -DTWO_FILE_COMMANDLINE or -D switches for other
+#   symbols listed in jconfig.h, if you prefer not to change jconfig.h.
+# If your compiler is non-ANSI, also see the .c.o rule below.
+
+# On HP-UX (and probably other SysV systems) the alternate malloc(3X) is a lot
+# faster than the standard malloc; this makes a noticeable difference in the
+# startup time when handling big noninterleaved images.  I say "-lmalloc" to
+# get the alternate allocator.  On most non-SysV systems you can just
+# define LDLIBS as empty.
