tazwok view libtazwok/libtazwok @ rev 555

2 # This is the SliTaz main library (/usr/lib/slitaz/libtaz).
3 # libtazwok is modular : see explanation of the function source_lib below.
4 #
5 # Author : Antoine Bodin <gokhlayeh@mailoo.org>
6 #
7 # Version : 0.0.1 (alpha1)
8 #
9 # Documentation : none (will be available with beta version)
10 # The documentation will include an explanation of all functions, how to
11 # use them and how to improve this library.
12 #
13 # Devnotes (suppress while beta is released) :
14 # Add a generic download script ? -> download from tazlito & tazwok
15 # Add a generic create/cleanup script for tmp files ?
16 # check_for (pkg on cmd line, pkg, receipt, etc.) -> tazwok,tazpkg,list
17 #
18 # Note: as the work is in progress some parts are dirty code or others
19 # are not finished. I will update this because we need the libdep.

22 # INITIALIZATION
23 ########################
24 # Load the Slitaz main configuration file : /etc/slitaz/slitaz.conf.
25 # Don't load it if an application is called by one already,
26 # to avoid options overwrite.

28 . /etc/slitaz/libtazwok.conf

30 # Load the command as some modules use it.
31 log_command="$0 $@"

33 # Define & create a temporary directory as it's used by report.

69 # This function should be used after sourcing libtaz to source modular
70 # libraries. Libtaz only sources main configuration files and contains only
71 # this function. The modular libraries should be put in the slitaz lib
72 # directory (/usr/lib/slitaz/libtazwok-modules).
73 #
74 # Usage : source_lib lib [lib2] [lib3] ...
75 #
76 # Description of libraries included with libtaz :
77 # commons : functions used by most SliTaz scripts
78 # get_option* : function to check & parse arguments of a command line
79 # report : display and log scripts in a configurable way
80 #
81 # * needs a code review, please don't use them for production : code can
82 # be hardly modified.
83 #
84 # All these libraries contains additional functions. Check them to
85 # know which ones and how to use them.
86 # More information will be available at beta release.
