Requirements
  
   This extension requires the c-client library to be installed.
   Grab the latest version from » ftp://ftp.cac.washington.edu/imap/
   and compile it.
  
  
   It's important that you do not copy the IMAP source files directly into
   the system include directory as there may be conflicts.  Instead, create
   a new directory inside the system include directory, such as 
   /usr/local/imap-2000b/ (location and name
   depend on your setup and IMAP version), and inside this new 
   directory create additional directories named lib/ 
   and include/.  From the c-client 
   directory from your IMAP source tree, copy all the *.h 
   files into include/ and all the 
   *.c files into lib/.  
   Additionally when you compiled IMAP, a file named
   c-client.a was created.  Also put this in the 
   lib/ directory but rename it as
   libc-client.a.
  
  Note: 
   
    To build the c-client library with SSL or/and Kerberos support read
    the docs supplied with the package.
   
  
  Note: 
   
    In Mandrake Linux, the IMAP library (libc-client.a)
    is compiled without Kerberos support. A separate version with SSL
    (client-PHP4.a) is installed. The library must
    be recompiled in order to add Kerberos support.
