2 # TazPkg - Tiny autonomous zone packages manager, hg.slitaz.org/tazpkg
3 # mkdb - TazPkg module
4 # Make TazPkg database for folder with *.tazpkg packages
7 # Input: $1 - path to folder contains *.tazpkg packages
8 # Output files in the $1 folder:
9 # packages.info
10 # packages.equiv
11 # descriptions.txt
12 # files.list.lzma
13 # IDs
14 # Do nothing if database already exists; force rebuild it with --forced option.
16 # DB format:
17 # ==========
19 # packages.info
20 # -------------
21 # Record is line; fields are tab-separated. Fields description:
22 # 1: package name
23 # 2: version with extra-version
24 # 3: category
25 # 4: short description
26 # 5: upstream web site
27 # 6: tags (space-separated)
28 # 7: packed and unpacked sizes (space-separated) in human readable format
29 # 8: depends
30 # 9: "release checksum"
31 #10: provide
33 # packages.equiv
34 # --------------
35 # This DB file used before package installation
36 # Record is line. Separator is "="
37 # Field 1 is package name to install (pkg1)
38 # Field 2 is space-separated list of items in the special format:
39 # a) pkg2:pkg3
40 # If pkg2 is installed, then install pkg3 instead of pkg1. Example:
41 # busybox=pam:busybox-pam
42 # If 'pam' is installed, then install 'busybox-pam' instead of 'busybox'
43 # b) pkg2
44 # If pkg2 already installed, then pkg1 will not be installed. Example:
45 # mysql=mariadb
46 # If 'mariadb' already installed, then 'mysql' will not be installed
47 # Complex rule example:
48 # ssh=pam:openssh-pam openssh pam:dropbear-pam dropbear
50 # descriptions.txt
51 # ----------------
52 # Field is line; record separator is empty line.
53 # First field is package name, rest - description itself.
54 # Empty lines in the description appended with space (" ") to avoid mess
55 # with end of record.
57 # files.list.lzma
58 # ---------------
59 # It is "files.list" compressed using lzma due to it's big size.
60 # Format of the files.list: record is line; field separator is ": ".
61 # First field is package name, second field is file path.
62 # There are DB records for all files installed with the package.
64 # packages.md5
65 #-------------
66 # Record is line; field separator is " ".
67 # First field is md5sum of the package file; second field is package file name.
68 # Actually, the type of checksum defined in variable $SUM and defaults to "md5".
