    Borland C++ compiler
    ---------------------
 
-   compile openssl
+   Ensure that your build environment is properly set up to use the compiler
+   and associated tools. PATH environment variable must include the path to
+   bin subdirectory of your compiler installation, eg: c:\Borland\BCC55\bin
 
-   Make sure you include the paths to curl/include and openssl/inc32 in
-   your bcc32.cnf file
+   It is advisable to set environment variable BCCDIR to the base path of
+   the compiler installation.
 
-   eg : -I"c:\Bcc55\include;c:\path_curl\include;c:\path_openssl\inc32"
+     set BCCDIR=c:\Borland\BCC55
 
-   Check to make sure that all of the sources listed in lib/Makefile.b32
-   are present in the /path_to_curl/lib directory. (Check the src
-   directory for missing ones.)
+   In order to build a plain vanilla version of curl and libcurl run the 
+   following command from curl's root directory:
 
-   Make sure the environment variable "BCCDIR" is set to the install
-   location for the compiler eg : c:\Borland\BCC55
+     make borland
 
-   command line:
-   make -f /path_to_curl/lib/Makefile-ssl.b32
+   To build curl and libcurl with zlib and OpenSSL support set environment
+   variables ZLIB_PATH and OPENSSL_PATH to the base subdirectories of the
+   already built zlib and OpenSSL libraries and from curl's root directory
+   run command:
 
-   compile simplessl.c with appropriate links
+     make borland-ssl-zlib
+
+   libcurl library will be built in 'lib' subdirectory while curl tool
+   is built in 'src' subdirectory. In order to use libcurl library it is
+   advisable to modify compiler's configuration file bcc32.cfg located
+   in c:\Borland\BCC55\bin to reflect the location of libraries include
+   paths for example the '-I' line could result in something like:
+
+     -I"c:\Borland\BCC55\include;c:\curl\include;c:\openssl\inc32"
+
+   bcc3.cfg '-L' line could also be modified to reflect the location of
+   of libcurl library resulting for example:
+
+     -L"c:\Borland\BCC55\lib;c:\curl\lib;c:\openssl\out32"
+
+   In order to build sample program 'simple.c' from the docs\examples
+   subdirectory run following command from mentioned subdirectory:
+
+     bcc32 simple.c libcurl.lib cw32mt.lib
+
+   In order to build sample program simplessl.c an SSL enabled libcurl
+   is required, as well as the OpenSSL libeay32.lib and ssleay32.lib
+   libraries.
 
-   c:\curl\docs\examples\> bcc32 -L c:\path_to_curl\lib\libcurl.lib
-                                 -L c:\borland\bcc55\lib\psdk\ws2_32.lib
-                                 -L c:\openssl\out32\libeay32.lib
-                                 -L c:\openssl\out32\ssleay32.lib
-                                 simplessl.c
