+ Environment Variables
+
+
+ There are some environment variables that you can customize to
+ fit your personal needs (e.g., default text editor, default
+ locale information, default time zone representation, etc.).
+ To customize these variables you need to edit your personal
+ profile (i.e., ~/.bash_profile) and set the
+ redefinition there. Notice that you may need to logout and
+ then do login again in order for the new variable values to
+ take effect.
+
+
+
+ Default text editor
+
+ The default text editor information is controlled by the
+ EDITOR environment variable. The
+ centos-art.sh script uses the default text
+ editor to edit subversion pre-commit messages, translation
+ files, documentation files, script files, and similar
+ text-based files.
+
+
+
+ If EDITOR environment variable is not set,
+ centos-art.sh script uses /usr/bin/vim as default text
+ editor. Otherwise, the following values are recognized by
+ centos-art.sh script:
+
+
+
+
+ /usr/bin/vim
+
+
+
+
+
+ /usr/bin/emacs
+
+
+
+
+
+ /usr/bin/nano
+
+
+
+
+
+
+
+ If no one of these values is set in the EDITOR
+ environment variable, the centos-art.sh
+ script uses /usr/bin/vim text editor, the one
+ installed by default in &TCD;.
+
+
+
+
+ Default locale information
+
+ The default locale information is controlled by the
+ LANG environment variable. This variable is
+ initially set in the installation process of &TCD;,
+ specifically in the Language step.
+ Generally, there is no need to customize this variable in your
+ personal profile. If you need to change the value of this
+ environment variable do it through the login screen of GNOME
+ Desktop Environment or the
+ system-config-language command.
+
+
+
+ The centos-art.sh script uses the
+ LANG environment variable to determine what
+ language to use for printing output messages from the script
+ itself, as well as the portable objects locations that need to
+ be updated or edited when you localize directory structures
+ inside the working copy of &TCAR;.
+
+
+
+
+ Default time zone representation
+
+ The time zone representation is a time correction applied to
+ the system time (stored in the BIOS clock) based on your
+ country location. This correction is specially useful to
+ distributed computers around the world that work together and
+ need to be syncronized in time to know when things happened.
+
+
+ &TCAR; is made of one server and several workstations spread
+ around the world. In order for all these workstations to know
+ when changes in the server took place, it is required that
+ they all set their system clocks to use the same time
+ information (e.g., through UTC (Coordinated Universal Time))
+ and set the time correction for their specific countries in
+ the operating system. Otherwise, it would be difficult to
+ know when something exactly happened.
+
+
+ Generally, setting the time information is a straight-forward
+ task and configuration tools provided by &TCD; do cover time
+ correction for most of the countries around the world.
+ However, if you need a time precision not provided by any of
+ the date and time configuration tools provided by &TCD; then,
+ you need to customize the TZ environment
+ variable in your personal profile to correct the time
+ information by yourself. The format of TZ
+ environment variable is described in tzset(3)
+ manual page.
