1 === The D Shared Software System ===
2
3 DSSS, the D Shared Software System, is a tool to ease the building,
4 installation, configuration and acquisition of D software.
5
6
7 == Building ==
8
9 There are plenty of tools for building D software. There's bud (previously
10 build), upon which DSSS is based, the antiquated make, and a plethora of other
11 tools capable of building D software. DSSS intends to be more generally useful
12 than any of them.
13
14  * DSSS eliminates the need to keep lists of source files, figuring them all
15    out by imports in source. It will even link in the proper libraries
16    automatically.
17  * DSSS can transparently build libraries from any D package.
18  * DSSS automatically generates .di (D import) files for libraries which cause
19    code using the library to link it in automatically.
20  * DSSS is based on the build tool 'rebuild', which, like bud, has a suite
21    of its own features which DSSS can employ.
22  * DSSS can automatically choose names for libraries generated from D packages
23    which will not conflict with libraries from other sources, or incompatible
24    compilers. So you do not need to concern yourself with library names.
25
26
27 == Installation ==
28
29 As compared to building software, there are few tools capable of installing D
30 software well.
31
32  * DSSS maintains a centralized repository of installed software, such that you
33    can use it in your software trivially. .di files and library files are all
34    managed by DSSS, as part of its effort to make imports map to library files
35    automatically.
36  * DSSS keeps track of all of the software that has been installed through
37    DSSS, so any of it can be uninstalled easily.
38
39
40 == Configuration ==
41
42 DSSS' build configuration file (dsss.conf) allows full use of version
43 statements from D. So, you can fine-tune your software to build precisely what
44 is necessary for the host system.
45
46
47 == Acquisition ==
48
49 In the spirit of Perl's CPAN or Ruby's Gems, DSSS has a central repository of
50 sources for D software. It maintains a list of software packages available,
51 where they can be acquired, and what packages/modules they provide. Because it
52 maintains a list of packages and modules, dependencies for a tool can be
53 installed as easily as:
54 $ dsss net deps
55
56 DSSS will then trace all of the software's D dependencies and install them.
57 This feature can of course also be used to install arbitrary software, such as:
58 $ dsss net install mango
59
60 Upon either of these commands, DSSS will download the software from its
61 upstream source, compile it, and install it.
62

64 == More Information ==
65
66 DSSS is available from http://www.dsource.org/projects/dsss . It is FOSS
67 (Free/Open Source Software) under a very permissive license. Its development
68 code base is maintained in subversion and can be checked out from the following
