 ## 5. The pkgman.sh file
-### 5.1. Functions
+### 5.1. Global dependencies
-#### 5.1.1. pkgupdt
+Because it gives system independent function to the system dependent package
+manager, the entire file depends on *PKG_MAN* variable, defining the package
+manager executable to use. Other variables giving command line parameters to
+use for the different function will also be nedeed and detailed for every
+function. All those variable are defined in a system dependant configuration
+file automatically called on script startup.
+
+### 5.2. Functions
+#### 5.2.1. pkgupdt
+That function calls the package manager to update package database.
+
+It depends on the *COM_UPDATE* variable wich define the parameters to use to
+accomplish that function.
+
+That function takes no parameters and any given parameters will be ignored.
+
+#### 5.2.2. pkginst
+That function installs using the package manager the packages given in
+parameters. The list of parameters are all considered as package names.
+
+If the *INSTALL_MODE* variable is set to "dev" the package manger will be
+called one package after the other. Elsewhere, it will be called once with
+the entire package list as parameter.
+
+The function depends on the *COM_INSTALL* variable wich define the parameter
+to use to accomplish that function.
+
+#### 5.2.3. pkgupgd
+That function calls the package manager to upgrade system.
+
+It depends on the *COM_UPGRADE* variable wich define the parameters to use to
+accomplish that function.
+
+That function takes no parameters and any given parameters will be ignored.
+
+#### 5.2.4. pkgrem
+That function uninstalls using the package manager the packages given in
+parameters. The list of parameters are all considered as package names.
+
+If the *INSTALL_MODE* variable is set to "dev" the package manger will be
+called one package after the other. Elsewhere, it will be called once with
+the entire package list as parameter.
+
+The function depends on the *COM_REMOVE* variable wich define the parameter
+to use to accomplish that function.
+
+#### 5.2.3. pkgupgd
+That function calls the package manager to remove no longer needed installed
+dependencies. Any package not manually installed is considered as a depndency.
+
+It depends on the *COM_AUTOREM* variable wich define the parameters to use to
+accomplish that function.
+
+That function takes no parameters and any given parameters will be ignored.

+## 6. The services.sh files
+### 6.1. Global dependencies
+That script relies on the *INIT_COM* variable, defining the program to use to
+manipulate services. It is defined in configuration file automatically called
+depending on your distribution. Nevertheless, even if it's system dependent,
+some distributions offers you to choose between different services call (and
+init system). Tested init systems are SystemV init, SystemD and UpStart. Thus,
+the originally UpStart "service" program tend to be available on many systems
+and is privileged.
