2 # TazPkg - Tiny autonomous zone packages manager, hg.slitaz.org/tazpkg
3 # get - TazPkg module
4 # Get package to the cache directory
7 # 1. "Plain packages" - compiled and packed on cook.slitaz.org using receipts.
8 #
9 # Recently added other type of packages: packages that can't be compiled due to the closed sources
10 # or due to the giant size of that sources. In this case special script: a) downloads package
11 # compiled for other Linux from official web site, b) converts this package to the TazPkg format,
12 # c) installs this package as "plain" package.
13 #
14 # 2. "Get-packages" - package contains only one special script for downloading/converting.
15 # Sometimes get-package can get some specified version of the package, sometimes - different
16 # (latest) version.
17 #
18 # Packages 1. and 2. can be found in the wok repository: http://hg.slitaz.org/wok/
19 #
20 # 3. "Extra" get-scripts. Next addition - only script, without packaging.
21 # Extra get-scripts repository: http://hg.slitaz.org/get-scripts/
22 # Extra get-scripts mirror: http://mirror.slitaz.org/packages/get/
23 #
24 # 4. Converted "extra" packages. Next addition - some packages like LibreOffice / OpenOffice are
25 # big to compile them like _1. "Plain packages"_ as well as big to convert them on the user side
26 # (you need a lot of time, CPU, and RAM) and sometimes it is unable on the weak user machines.
27 # So, some selected and free packages are converted on the SliTaz server side, packaged and
28 # are ready to download by any user: http://mirror.slitaz.org/packages/extra/
29 #
30 #
31 # Algorithm to get package:
32 # - search package in question in the mirrored packages list, download if exists;
33 # - search "get-package" in the mirrored packages list, download if exists;
34 # - search package in the "extra" get-scripts list, download if exists and run it, get the package.
35 #
36 # Note, here doubling. Imagine, you may wanted "palemoon" package.
37 # 1. No "plain package";
38 # 2. Existing "get-palemoon" package;
39 # 3. Existing "palemoon" extra get-script;
40 # 4. Existing "palemoon" extra converted package.
41 # User will get 2. He can specify "--extra" option to get 3.
42 # FIXME: do something with doubling.
