Extracting .tar.gz Archives
epkg has the ability to extract .tar.gz
Archives. This makes it extremely easy to install new Encaps, since
you can do it all in one step. Instead of extracting the archive
manually into /usr/local/encap and then invoking
epkg, you can simply say epkg sed-3.02.tar.gz.
This will tell epkg to extract the new archive into the
Encap Source Directory, remove the symbolic links for any old versions
of the package, and install the symbolic links for the new version.
Note that epkg can be configured at compile time to use the
libtar and zlib libraries so that no external
binaries are needed. The precompiled binaries of epkg which
are available from the epkg web page were
configured this way. However, if epkg is built without this
code, your system's tar and gzip binaries must be
in your path when you invoke epkg.
