DISTRIBUTION CONTENTS
-----------------------------------------------------------------------

This Pine distribution includes:

bin        - Compiled binaries are found here
build      - Shell script to compile Pine and Pico
contrib    - Contributed ports and additions
doc        - Documentation directory. The main documentation is tech-notes.txt
imap	   - Source tree containing C-Client IMAP implementation
makefile   - In case make is tried to build Pine and Pico
pico       - The Pico and Pilot source directory
pine       - The Pine source directory

Most of the documentation is in doc/tech-notes.txt. It is not user level
documentation, but there are things in it some users might find useful.
There are also instructions for building and porting Pine.  The directory
doc/tech-notes contains source for doc/tech-notes.txt in HTML format which
can be viewed via a Web browser by opening doc/tech-notes/index.html.


-----------------------------------------------------------------------
PRELIMINARIES
-----------------------------------------------------------------------

If you are reading this, you have presumably succeeded in extracting
the distribution from the compressed tar archive file, via the following 
command, or equivalent:

        tar zxf pine.tar.z

Some of the instructions that follow assume that your current workding 
directory is the pineX.XX directory created by the un-tar process above.


-----------------------------------------------------------------------
BUILD SYNTAX
-----------------------------------------------------------------------

A shell interpreter script called "build" is used to compile Pine and the
other programs in the distribution. The build script is also responsible
for building operating system specific symbolic links into the
imap/c-client source tree.

Usage: build <make-options> <target-platform>

<target-platform> may be one of the ports listed in doc/pine-ports or
  clean   Clean up object files and such.
          Also, a good way to rebuild Pine/Pico from scratch.

"Build" by itself with no arguments is the same as typing in the previous
build command with the arguments used then.

To build Pine and Pico the command "build xxx" should work where xxx
is one of the targets. For example "build gul" to build Pine for Ultrix.

There are three pieces of Pine which are optionally included. When
you build Pine, the three lines

       Including SSL functionality
       Including LDAP functionality
       Including Kerberos5 functionality

should be printed early in the build process if the corresponding
piece is being included.  (See below for more about these options.)


-----------------------------------------------------------------------
INCLUDING LDAP
-----------------------------------------------------------------------

If you are attempting to compile in the LDAP functionality in pine, you
should get the OpenLDAP source, set up the libldap and liblber libraries,
and the include files. A usually easy way to do that is

  ./configure  --disable-slapd --disable-slurpd --without-kerberos --without-threads
  make depend
  make

The configure line may not be right for you.

Add a symlink called ldap to this directory (the directory with this
build file in it) which points to the ldap installation. That is, the directory
ldap points to should contain the directories include and libraries. For
example, the command to create the symlink might be something like

  ln -s /path/to/openldap/source/openldap-2.0.7 ldap

Alternatively, you may use the older Univ. of Michigan ldap-3.3 source and
put it in a directory called "ldap" in this top-level pine directory. Or
you could put a symlink pointing from here to the actual location. The
include files should show up in ldap/include and the libraries in
ldap/libraries.

Alternatively, you can try using the Netscape Directory SDK 1.0 (or probably
3.0 when it is ready) by putting the include files in ldap/include and
libldap.a in ldap/libraries. This build script will attempt to notice that
you are not using ldap-3.3 and leave out liblber.a, which is required when
using ldap-3.3.

Alternatively, OpenLDAP may already be included in your system libraries.
Solaris 8 is apparently set up this way. The script contrib/ldap-setup,
which is called by the build script, tries to detect this automatically.
It causes ldap-setup to exit with value 3 and the build script notices
that and sets the appropriate arguments.


-----------------------------------------------------------------------
INCLUDING KERBEROS
-----------------------------------------------------------------------

If you are attempting to compile in Kerberos5 functionality, put a symlink
called krb5 pointing from the directory containg the "build" script, to
the location of the Kerberos includes and libraries. The expected files
should be in krb5/include and krb5/lib. On many systems, this would be
accomplished with

  ln -s /usr/local krb5

However, the location (as well as the tools available to find
the needed files) will vary from one system to another.
For example, on RedHat Linux 7.2, you could try the command

        locate krb5.h

and discover that the Kerberos libraries are in the directory
/usr/kerberos  (e.g. /usr/kerberos/include/krb5.h )
Therefore the needed command for this system would be:

        ln -s /usr/kerberos krb5


-----------------------------------------------------------------------
INCLUDING SSL
-----------------------------------------------------------------------

An attempt is made to include SSL support automatically. If OpenSSL is
installed in /usr/local/ssl then it is used. It doesn't make sense to use
the same "linking" mechanism as is used for LDAP and Kerberos, since the
SSLDIR is used at run-time, not just compile-time. You can change the
directory with the build argument:

  SSLDIR=/some/directory

In other words, the build command would be:

  ./build SSLDIR=/some/directory target

where target is one of the 3-letter target names found in doc/pine-ports.

The assumption is that the certs directory is in SSLDIR/certs, the include
directory is SSLDIR/include, and the library directory is SSLDIR/lib.
You can change those assumptions with:

  SSLCERTS=certs_directory
  SSLINCLUDE=include_directory and
  SSLLIB=ssl_library_directory

You can override the automatic inclusion of SSL by including the
argument NOSSL. For example:

  ./build NOSSL target

The possible values for SSLTYPE are:

  none       no SSL support, the default
  unix       SSL support using OpenSSL
  nopwd      SSL support using OpenSSL, and plaintext authentication permitted
               only in SSL or TLS sessions.
  sco        link SSL before other libraries for SCO
  sco.nopwd  same as nopwd

Usually SSLTYPE will get set automatically by the script.

Note: The "nopwd" SSLTYPE is similar to "unix" except that it compiles
the IMAP server (imapd) so that plaintext authentication is only permitted 
if the session is encrypted via SSL or TLS.


-----------------------------------------------------------------------
EXTRAS
-----------------------------------------------------------------------

There are some other arguments which you may find useful. These four
usually aren't set to anything

  EXTRACFLAGS=
  EXTRALDFLAGS=

As an example, it should be ok to move string constants into a read-only
area because we don't think there are any instances where Pine modifies
a string constant. So you could pass a flag to your compiler telling it
to do this. With the AIX a41 port, you could pass the extra build argument

  EXTRACFLAGS=-qro

to accomplish this.

DEBUG applies only to pico and pine sub-makes. It typically defaults to

  DEBUG="-g -DDEBUG"

which causes symbol table information and debugging code to be compiled
into pine. That is what we use in our production versions of pine, because
the symbol table information makes it easier to analyze core dumps, and the
debugging code makes it possible to have Pine produce debug files. But if
you wanted an optimized version that produced no debug files you could use
the argument

  DEBUG=-O

The argument

  EXTRASPECIALS=

can be used to pass arguments to the c-client make which aren't provided
for in this build script. For example, if you want to change the FRIZZLE
parameter (a made-up argument name which the c-client make uses) you might 
be tempted to type something like

  build FRIZZLE=cruft target

This does work with make on some platforms, but not on others.
Some makes seem to pass the arguments on to sub-makes, others don't.
If that doesn't work, then EXTRASPECIALS is for you.

  build EXTRASPECIALS="FRIZZLE=cruft" target

An additional warning. There are some arguments which are overridden
unconditionally in the sub-makes. Hopefully none of the arguments mentioned
above falls in this category, but it is something to look out for if you
are having trouble.


-----------------------------------------------------------------------
RESULTING EXECUTABLES
-----------------------------------------------------------------------

The executables built by the build script are:

 pine   The Pine mailer. Once compiled this should work just fine on
        your system with no other files than this binary, and no
        modifications to your system. Optionally you may create two
        configuration files, /usr/local/lib/pine.conf and 
        /usr/local/lib/pine.info. See the documentation for details.
 
 pico   The standalone editor similar to the Pine message composer.
        This is a very simple straight forward text editor.
 
 pilot  The standalone file system navigator.
 
 imapd  The IMAP daemon. If you want to run Pine in client/server mode,
        this is the daemon to run on the server. Installing this
        requires system privileges and modifications to /etc/services.
        See doc/tech-notes for more details.
 
 mtest  The test IMAP client, an absolutely minimal mail client, useful
        for debugging.

In general you should be able to just copy the Pine and Pico binaries
to the place you keep your other local binaries. /usr/local/bin is a
likely place.
