     20 <h2> What is it&nbsp;? </h2>
     21 
     22 <p>
     23  skalibs is a package centralizing the free software / open source C development
     24 files used for building all software at skarnet.org: it contains essentially
     25 general-purpose libraries.
     26 You will need to install skalibs if you plan to build skarnet.org software.
     27  The point is that you won't have to download and compile big libraries, and care
     28 about portability issues,
     29 everytime you need to build a package: do it only once.
     30 </p>
     31 
     32 <p>
     33  skalibs can also be used as a sound basic start for C development. There
     34 are a lot of general-purpose libraries out there; but if your main goal is
     35 to produce <em>small</em> and <em>secure</em> C code with a focus on system
     36 programming, skalibs might be for you.

     51 </ul>
     52 
     53 <h3> Licensing </h3>

     59 
     60 <h3> Download </h3>
     61 
     62 <ul>
     63  <li> The current released version of skalibs is <a href="skalibs-2.14.2.0.tar.gz">2.14.2.0</a>. </li>
     64  <li> Alternatively, you can checkout a copy of the
     65 <a href="//git.skarnet.org/cgi-bin/cgit.cgi/skalibs/">skalibs
     66 git repository</a>:
     67 <pre> git clone git://git.skarnet.org/skalibs </pre> </li>
     68  <li> There's also a
     69 <a href="https://github.com/skarnet/skalibs">GitHub mirror</a>
     70 of the skalibs git repository. </li>
     71 </ul>
     72 
     73 <h3> Compilation </h3>
     74 
     75 <ul>
     76  <li> See the enclosed INSTALL file for installation details. </li>
     77  <li> skalibs sports a few uncommon options to its <tt>./configure</tt> script.
     78 <a href="flags.html">This page</a> documents them in detail. </li>
     79 </ul>
     80 
     81 <h3> Upgrade notes </h3>
     82 
     83 <ul>
     84  <li> <a href="upgrade.html">This page</a> lists the differences to be aware of between
     85 the previous versions of skalibs and the current one. </li>
     86 </ul>
     87 
     88 <h3> Cross-compilation </h3>
     89 
     90 <p>
     91  Cross-compilation is tricky. skalibs provides system-agnostic interfaces, so all the
     92 other skarnet.org packages cross-compile easily; but some effort needs to be made to
     93 cross-compile skalibs, see <a href="crosscompile.html">this page</a>.

    108 
    109 <p>
    110  Here are a few other libraries originating from the same place as
    111 skalibs, i.e. people start to reuse and package, or rewrite,
    112 <a href="djblegacy.html">code from Dan J. Bernstein</a>, and then patch
    113 after patch, addition after addition, the code evolves into a project
    114 of its own:
