+
+===============================================================================
+
+To build this code after doing a Git clone, run:
+
+    $ ./acprep update
+
+If you try to configure/build on your own, you are almost certainly going to
+run into problems.  In future, you can run this command again and it will keep
+you updated with the very latest version.
+
+===============================================================================
+
+                                    F.A.Q.
+
+   ----------------------------------------------------------------------
+
+ - Q: The build fails saying it can't find utf8.h
+
+   A: You didn't run ./acprep update.
+
+   ----------------------------------------------------------------------
+
+ - Q: Configure fails saying it can't find boost_regex
+
+   A: Look in config.log and search for "boost_regex", then scroll down a bit
+      until you see the exact compile error.  Usually it's failing because
+      your include directory is different from anything acprep is expecting to
+      see.  It could also be failing because your Boost libraries have a
+      custom "suffix" on them.
+
+      Let's say your Boost was installed in ~/boost, and every library has the
+      suffix '-xgcc42'.  This is what you would run:
+
+        CPPFLAGS=-I$HOME/boost acprep --boost=xgcc42 update
+
+   ----------------------------------------------------------------------
+
+ - Q: Configure fails saying it can't find MPFR
+
+   A: You need MPFR version 2.4.0 or higher.  This version does not come with
+      most Debian distributions, so you will need to build it.
+
+   ----------------------------------------------------------------------
+
+ - Q: Something else fails, or Ledger crashes on startup
+
+   A: This, I am most interested in hearing about.  Please e-mail me a copy of
+      config.log and your build log to <johnw@newartisans.com>.  Also, if
+      Ledger is crashing, try running it under gdb like so:
+
+        $ gdb ledger
+        (gdb) run <ARGS TO LEDGER>
+        ... runs till crash ...
+        (gdb) bt
+
+      Send me that backtrace output, and the output from "ledger --version".

+# Script for automatically preparing the sources for compilation by
+# performing the myrid of necessary steps.  The script attempts to
+# detect proper version support, and outputs warnings about particular
+# systems that have autotool peculiarities.
+#
+# Basically, if everything is set up and installed correctly, the
+# script will validate that minimum versions of the GNU Build System
+# tools are installed, account for several common configuration
+# issues, and then simply run autoreconf for you.
+#
+# If autoreconf fails, which can happen for many valid configurations,
+# this script proceeds to run manual preparation steps effectively
+# providing a POSIX shell script (mostly complete) reimplementation of
+# autoreconf.
+#
+# The AUTORECONF, AUTOCONF, AUTOMAKE, LIBTOOLIZE, ACLOCAL, AUTOHEADER
+# environment variables and corresponding _OPTIONS variables (e.g.
+# AUTORECONF_OPTIONS) may be used to override the default automatic
+# detection behaviors.  Similarly the _VERSION variables will override
+# the minimum required version numbers.
+#
+# Examples:
+#
+#   To obtain help on usage:
+#     ./autogen.sh --help
+#
+#   To obtain verbose output:
+#     ./autogen.sh --verbose
+#
+#   To skip autoreconf and prepare manually:
+#     AUTORECONF=false ./autogen.sh
+#
+#   To verbosely try running with an older (unsupported) autoconf:
+#     AUTOCONF_VERSION=2.50 ./autogen.sh --verbose
+#
