+Notes on making a new release of libarchive
+===========================================
+
+The following serves as a guide for libarchive developers on the general
+process to be followed when making a new release of libarchive.
+
+* Update build/version with the version number of the release to be made.
+* If the library's ABI has changed, the library's soname major version *MUST*
+  be updated. Update configure.ac and CMakeLists.txt appropriately.
+  - For configure.ac, the variable ARCHIVE_INTERFACE needs to be updated.
+  - For CMakeLists.txt, the variable INTERFACE_VERSION needs to be updated.
+* Update the entries in the NEWS file accordingly.
+* Run `build/makerelease.sh` from the top source directory. Running this script
+  will do the following.
+  - Removes all Makefile.am development build specific CFLAGS from
+    Makefile.am.
+  - Update configure scripts and header files with the appropriate version
+    number from build/version.
+  - Rebuild the documentation directory.
+  - Runs a full cmake build and test.
+  - Runs a full autotools build and test.
+  - Builds the .tar.gz and .zip distribution files.
+* Commit all changed files into git.
+  - This should be build/version, NEWS, and the files edited by running
+    build/makerelease.sh.
+* Tag the release appropriately. The tag should also have an appropriate
+  message.
+  - The git command is as follows:
+    $ git tag -m "Libarchive <version>" v<version>
+    Replace <version> with the version to be released.
+* Copy all the generated wiki files and commit them into the libarchive.wiki
+  repository. Overwrite any preexisting files with the same name (these files
+  are always autogenerated from the libarchive release after every release).
+* Update the libarchive.org website accordingly.
+* Make an announcement to the libarchive-announce mailing list.

+# SYNOPSIS
+#
+#   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   For every FLAG1, FLAG2 it is checked whether the compiler works with the
+#   flag.  If it does, the flag is added FLAGS-VARIABLE
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  During the check the flag is always added to the
+#   current language's flags.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: This macro depends on the AX_APPEND_FLAG and
+#   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
+#   AX_APPEND_LINK_FLAGS.

+#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
+#
+# DESCRIPTION
+#
+#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
+#   added in between.
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
+#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
+#   FLAG.

+#   AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+#   been defined and thus are available for use.  This avoids random issues
+#   where a macro isn't expanded.  Instead the configure script emits a
+#   non-fatal:
+#
+#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+#   It's like AC_REQUIRE except it doesn't expand the required macro.
+#

+# SYNOPSIS
+#
+#   AX_COMPILE_CHECK_SIZEOF(TYPE [, HEADERS [, EXTRA_SIZES...]])
+#
+# DESCRIPTION
+#
+#   This macro checks for the size of TYPE using compile checks, not run
+#   checks. You can supply extra HEADERS to look into. the check will cycle
+#   through 1 2 4 8 16 and any EXTRA_SIZES the user supplies. If a match is
+#   found, it will #define SIZEOF_`TYPE' to that value. Otherwise it will
+#   emit a configure time error indicating the size of the type could not be
+#   determined.
+#
+#   The trick is that C will not allow duplicate case labels. While this is
+#   valid C code:
+#
+#     switch (0) case 0: case 1:;
+#
+#   The following is not:
+#
+#     switch (0) case 0: case 0:;
+#
+#   Thus, the AC_COMPILE_IFELSE will fail if the currently tried size does
+#   not match.
+#
+#   Here is an example skeleton configure.in script, demonstrating the
+#   macro's usage:
+#
+#     AC_PROG_CC
+#     AC_CHECK_HEADERS(stddef.h unistd.h)
+#     AC_TYPE_SIZE_T
+#     AC_CHECK_TYPE(ssize_t, int)
