26// You can specify all the values or you can default the Revision and Build Numbers
27// by using the '*' as shown below:
28
29[assembly: AssemblyVersion("1.0.*")]

31//
32// In order to sign your assembly you must specify a key to use. Refer to the
33// Microsoft .NET Framework documentation for more information on assembly signing.
34//
35// Use the attributes below to control which key is used for signing.
36//
37// Notes:
38// (*) If no key is specified, the assembly is not signed.
39// (*) KeyName refers to a key that has been installed in the Crypto Service
40// Provider (CSP) on your machine. KeyFile refers to a file which contains
41// a key.
42// (*) If the KeyFile and the KeyName values are both specified, the
43// following processing occurs:
44// (1) If the KeyName can be found in the CSP, that key is used.
45// (2) If the KeyName does not exist and the KeyFile does exist, the key
46// in the KeyFile is installed into the CSP and used.
47// (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
48// When specifying the KeyFile, the location of the KeyFile should be
49// relative to the project output directory which is
50// %Project Directory%\obj\<configuration>. For example, if your KeyFile is
51// located in the project directory, you would specify the AssemblyKeyFile
52// attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
53// (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
54// documentation for more information on this.

1This directory contains a .Net wrapper class library for the ZLib1.dll
2
3The wrapper includes support for inflating/deflating memory buffers,
4.Net streaming wrappers for the gz streams part of zlib, and wrappers
5for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.

18Unit tests:
19-----------
20The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
21To include unit tests in the build, define nunit before building.
22
23
24Build instructions:
25-------------------
26
271. Using Visual Studio.Net 2003:
28 Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
29 will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
30 you are building the release or debug version of the library. Check
31 DotZLib/UnitTests.cs for instructions on how to include unit tests in the
32 build.
33
342. Using NAnt:
35 Open a command prompt with access to the build environment and run nant
36 in the same directory as the DotZLib.build file.
37 You can define 2 properties on the nant command-line to control the build:
38 debug={true|false} to toggle between release/debug builds (default=true).
39 nunit={true|false} to include or esclude unit tests (default=true).
40 Also the target clean will remove binaries.
41 Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
42 or ./DotZLib/bin/debug, depending on whether you are building the release
43 or debug version of the library.
44
45 Examples:
46 nant -D:debug=false -D:nunit=false
47 will build a release mode version of the library without unit tests.
48 nant
49 will build a debug version of the library with unit tests
50 nant clean
51 will remove all previously built files.
