= Readme (italiano) =
Compilare un programma per linux da sorgente e' semplice: il piu' delle
volte e' sufficiente dare:

./configure make su make install

Quest'ultimo comando installa effettivamente i file nel sistema. Raramente
pero' l'autore offre la possibilita' di dare "make uninstall", quindi
la procedura di disinstallazione non e' affatto semplice.

SafeInstall sostituisce "make install", ma anziche' installare il software
crea un pacchetto .tgz per Slackware, che puo' essere installato con
"installpkg" e rimosso con "removepkg". In questo modo il sistema resta
pulito e si puo' tenere traccia del software installato nel sistema.

SafeInstall esegue il "make install" da utente normale, redirigendo
l'installazione in una directory temporanea della home directory
dell'utente, dalla quale poi crea effettivamente il pacchetto. Senza
permessi di root, non esiste il rischio che il "make install" sparga
in giro per il sistema qualche file, contribuendo cosi' alla "pulizia"
del sistema.

SafeInstall necessita dei permessi di root esclusivamente per settare
correttamente i permessi dei file contenuti nel pacchetto.

Prima di creare effettivamente il pacchetto, e' possibile aggiungere o
togliere files (per esempio eliminare locales, pagine man, etc.)

Il pacchetto viene salvato nella home directory dell'utente, e
contemporaneamente vengono creati 2 file: "<nomepacchetto>.log" e
"<nomepacchetto>.err" contenenti i dettagli relativi all'installazione.
= Readme (inglese) =
Compiling a linux software from source is easy: most of the times you
just need to type:
<pre>
./configure
make
su
make install
</pre>
The last command installs all the files in your system. Unfortunately,
only a few program's authors add an uninstall rule to their Makefile,
so removing the software isn't easy.

SafeInstall takes the place of "make install", but instead of installing
it builds a Slackware package, which can be installed with "installpkg"
and removed with "removepkg". This way the system remains "clean".

SafeInstall executes "make install" with normal user permissions,
redirecting the installation to a temporary directory in the user's
home, from which the package is built. Without root permissions, the
"make install" can't mess up the system with files installed anywhere.

SafeInstall needs root permission just for setting package files and
directories permissions.

Before creating the package you can manually modify the package content
(e.g. removing locales, man pages, ...).

The package will be saved in your home directory, and at the same time
two files will be created: "<packagename>.log" e "<packagename>.err",
containing installation details.
