While there is an install target, it's present only because Automake
provides it automatically.  Its use is not recommended.  Instead, the code
in this package is intended to be copied into your package and refreshed
from the latest release of rra-c-util for each release.

You can obviously copy the code and integrate it however works best for
your package and your build system.  Here's how I do it for my packages as
an example:

* Create a portable directory and copy `macros.h`, `system.h`,
  `stdbool.h`, and `dummy.c` along with whatever additional functions that
  your package uses that may not be present on all systems.  If you use
  much of the `util` directory (see below), you'll need `asprintf.c`,
  `reallocarray.c`, and `snprintf.c` at least.  If you use
  `util/network.c`, you'll also need `getaddrinfo.c`, `getaddrinfo.h`,
  `getnameinfo.c`, `getnameinfo.h`, `inet_*.c`, and `socket.h`.  You'll
  need `winsock.c` for networking portability to Windows.

* Copy the necessary portions of `configure.ac` from this package into
  your package.  `configure.ac` is commented to try to give you a guide
  for what you need to copy over.  You will also need to make an `m4`
  subdirectory, add the code to `configure.ac` to load Autoconf macros
  from `m4`, and copy over `m4/snprintf.m4` and possibly `m4/socket.m4`
  and `m4/inet-ntoa.m4`.

* Copy the code from `Makefile.am` for building `libportable.a` into your
  package and be sure to link your package binaries with `libportable.a`.
  If you include this code in a shared library, you'll need to build
  `libportable.la` instead; see the Automake manual for the differences.
  You'll need to change `LIBRARIES` to `LTLIBRARIES` and `LIBOBJS` to
  `LTLIBOBJS` in addition to renaming the targets.

* Create a `util` directory and copy over the portions of the utility
  library that you want.  You will probably need `messages.[ch]` and
  `xmalloc.[ch]` if you copy anything over at all, since most of the rest
  of the library uses those.  You will also need `m4/vamacros.m4` if you
  use `messages.[ch]`.

* Copy the code from `Makefile.am` for building `libutil.a` into your
  package and be sure to link your package binaries with `libutil.a`.  As
  with `libportable.a`, if you want to use the utility functions in a
  shared library, you'll need to instead build `libutil.la` and change
  some of the Automake variables.

* If your package uses a TAP-based test suite written in C, consider using
  the additional TAP utility functions in `tests/tap` (specifically
  `messages.*`, `process.*`, and `string.*`).

* If you're using the Kerberos portability code, copy over
  `portable/krb5.h`, `portable/krb5-extra.c`, `m4/krb5.m4`,
  `m4/lib-depends.m4`, `m4/lib-pathname.m4`, and optionally
  `util/messages-krb5.[ch]`.  You'll also need the relevant fragments of
  `configure.ac`.  You may want to remove some things from `krb5.h` and
  `krb5-extra.c` the corresponding configure checks if your code doesn't
  need all of those functions.  If you need `krb5_get_renewed_creds`, also
  copy over `krb5-renew.c`.  Don't forget to add `$(KRB5_CPPFLAGS)` to
  `CPPFLAGS` for `libportable` and possibly `libutil`, and if you're
  building a shared library, also add `$(KRB5_LDFLAGS)` to `LDFLAGS` and
  `$(KRB5_LIBS)` to `LIBADD` for those libraries.

  For a Kerberos-enabled test suite, also consider copying the
  `kerberos.*` libraries in `tests/tap` for a Kerberos-enabled test suite.
  If you want to use `kerberos_generate_conf` from `tests/tap/kerberos.c`,
  also copy over `tests/data/generate-krb5-conf`.

* For testing that requires making Kerberos administrative changes,
  consider copying over the `kadmin.*` libraries in `tests/tap`.

* For testing packages that use remctl, see the `tests/tap/remctl.c` and
  `tests/tap/remctl.h` files for C tests and `tests/tap/remctl.sh` for
  shell scripts.

* If you're using the kafs portability code, copy over the `kafs`
  directory, `m4/kafs.m4`, `m4/lib-pathname.m4`, `portable/k_haspag.c`,
  the code to build kafs from `Makefile.am`, and the relevant fragments of
  `configure.ac`.

* If you're using the PAM portability code, copy over `pam-util/*`,
  `portable/pam*`, `m4/pam-const.m4`, and the relevant fragments of
  `configure.ac`.

* Copy over any other Autoconf macros that you want to use in your
  package from the m4 directory.

* Copy over any generic tests from `tests/docs` and `tests/perl` that are
  appropriate for your package.  If you use any of these, also copy over
  the `tests/tap/perl` directory and `tests/data/perl.conf` (and customize
  the latter for your package).

* If the package embeds a Perl module, copy over any tests from the
  `perl/t` directory that are applicable.  This can provide generic
  testing of the embedded Perl module using Perl's own test
  infrastructure.  If you use any of these, also copy over the
  `perl/t/data/perl.conf` file and customize it for your package.  You
  will need to arrange for `perl/t/data` to contain copies of the
  `perlcriticrc` and `perltidyrc` files, either by making copies of the
  files from `tests/data` or by using make to copy them.

I also copy over all the relevant tests from the `tests` directory and the
build machinery for them from `Makefile.am` so that the portability and
utility layer are tested along with the rest of the package.  The test
driver should come from C TAP Harness.
