12 ║│ offered by libxml2 and libxslt. Beyond this, only programs │║
13 ║│ required by Posix are required, altho there is a chance of │║
14 ║│ version incompatibilities. The full list of program │║
15 ║│ requirements is as follows :— │║
16 ║│ │║
17 ║│ • awk │║
18 ║│ • cat │║
19 ║│ • cksum │║
20 ║│ • cp │║
21 ║│ • date │║
22 ║│ • echo │║
23 ║│ • file │║
24 ║│ • find │║
25 ║│ • git (optional) │║
26 ║│ • ln │║
27 ║│ • mkdir (requires support for `-p´) │║

40 ║│ • xmlcatalog (provided by libxml2) │║
41 ║│ • xmllint (provided by libxml2) │║
42 ║│ • xsltproc (provided by libxslt) │║
43 ║│ │║
44 ║│ In all cases, you can supply your own version of any │║
45 ║│ program `program´ by overriding the corresponding variable │║
46 ║│ `PROGRAM´ when calling Make. │║
47 ║╰────────────────────────────────────────────────────────────╯║
48 ╟┬ ¶ Usage ───────────────────────────────────────────────────┬╢
49 ║│ │║
50 ║│ • `make all´ (default): Compile, but do not install, all │║
51 ║│ files. │║
52 ║│ │║
53 ║│ • `make clean´: Remove `BUILDDIR´. │║
54 ║│ │║
55 ║│ • `make gone´: Remove `BUILDDIR´ and installed files. │║
56 ║│ │║
57 ║│ • `make help´: Print this message. │║
58 ║│ │║
59 ║│ • `make install´: Compile all files and install in │║
60 ║│ `DESTDIR´. │║
61 ║│ │║
62 ║│ • `make list´: List all recognized source files and their │║
63 ║│ classification (including media type and dependencies). │║
64 ║│ │║
65 ║│ • `make uninstall´: Remove installed files, but not │║
66 ║│ `BUILDDIR´. │║
67 ║│ │║
68 ║│ Set `VERBOSE=1´ to see the text of commands as they are │║
69 ║│ executed. │║
70 ║│ │║
71 ║│ See `README.markdown´ for a more involved description of │║
72 ║│ the capabilities and configuration of this program. │║
