+#
+# Notes:
+#
+# * Compilation Defines:
+#
+# FAKE_STAT
+# - Enables time faking also for files' timestamps.
+#
+# NO_ATFILE
+# - Disables support for the fstatat() group of functions
+#
+# PTHREAD_SINGLETHREADED_TIME
+# - Define this if you want to single-thread time() ... there ARE
+# possible caching side-effects in a multithreaded environment
+# without this, but the performance impact may require you to
+# try it unsynchronized.
+#
+# FAKE_INTERNAL_CALLS
+# - Also intercept libc internal __functions, e.g. not just time(),
+# but also __time(). Enhances compatibility with applications
+# that make use of low-level system calls, such as Java Virtual
+# Machines.
+#
+# FAKE_SLEEP
+# - Also intercept sleep(), nanosleep(), usleep(), alarm(), [p]poll()
+#
+# FAKE_TIMERS
+# - Also intercept timer_settime() and timer_gettime()
+#
+# FAKE_PTHREAD
+# - Intercept pthread_cond_timedwait
+#
+# MULTI_ARCH
+# - If MULTI_ARCH is set, the faketime wrapper program will put a literal
+# $LIB into the LD_PRELOAD environment variable it creates, which makes
+# ld automatically choose the correct library version to use for the
+# target binary. Use for Linux platforms with Multi-Arch support only!
+#
+# * Compilation addition: second libMT target added for building the pthread-
+# enabled library as a separate library
+#
+# * Compilation switch change: previous versions compiled using '-nostartfiles'
+# This is no longer the case since there is a 'startup' constructor for the library
+# which is used to activate the start-at times when specified. This also initializes
+# the dynamic disabling of the FAKE_STAT calls.
+#
+# By default, libfaketime will be compiled for your system's default architecture.
+# To build 32-bit libraries and binaries, add -m32 to CFLAGS and LDFLAGS.
+#
+# Change PREFIX to where you want libfaketime (libraries and wrapper binary) installed.
+# LIBDIRNAME is relative to PREFIX. The default is to install into $PREFIX/lib/faketime,
+# but you can set LIBDIRNAME to, e.g., /lib64 if you want to install it elsewhere.
+# LIBDIRNAME has been introduced to support MultiLib systems. Please do not change the
+# default value on MultiArch systems.

+ * the hash function as it applies to the key domain).
+ *
+ * With the items distributed into more buckets, the chain length

+ * Since the ideal chain length is an integer, we want to calculate

+ * hash, so to calculate ceil(n/b) with integers we could write
+ *
+ * ceil(n/b) = (n/b) + ((n%b)?1:0)
