-
-"$colorstart"DESCRIPTION"$colorstop"
-
-	Vasile is an acronym for ** Versatile Advanced Script for Iso and Latest Enchantments **
-
-"$colorstart"OPTIONS"$colorstop"
-	"$colorstart"--makepkg"$colorstop" ["$colorstart"package(s)"$colorstop"]
-		This option will allow you to build a package or multiple packages in an overlayfs mounted squashfs chroot jail.
-
-		It must be run in the folder where the squashfs chroot jail resides, or else it will fail to mount the squahfs chroot jail and build the package(s).
-
-		The squashfs chroot jail and the md5sum checksum file are hardcored into "$colorstart"libvasile"$colorstop", but you may want to change them to suit your needs.
-
-		You MUST provide package(s) to build as arguments, or else vasile will only mount the chroot jail
-
-		Examples :
-			"$colorstart"vasile --makepkg wine"$colorstop"
-			"$colorstart"vasile --makepkg wine playonlinux q4wine"$colorstop"
-
-		If the package(s) is/are already built, it will not build it/them again (unless newer version(s) is/are available), but install it/them into squahfs chroot jail
-
-		If the package(s) you want to build depends on any already built package(s) it will make use of it/them to satisfy the required dependencies.
-
-	"$colorstart"--makeiso"$colorstop"
-		This option will allow you to build a live iso image based on the squashfs chroot jail.
-
-		It must be run in the folder where the squashfs chroot jail resides, or else it will fail to rsync the contents of it and build the iso image.
-
-		It is not fully automatic, it will only rsync the contents of the squashfs chroot jail, chroot into it, and let you install packages you want into the iso image.
-		There are some predefined package sets available in "$colorstart"/etc/portage/sets"$colorstop". Adjust them to suit your needs.
-
-		It will ALLWAYS use package(s) built with "$colorstart"--makepkg"$colorstop" option. When you are happy with package selection, just exit the chroot environment and
-		the live filesystem will be compressed, live services will be autoenabled, live bootloader autoconfigured and in the end live iso image will be built. You will find
-		a list of predefined live services list hardcoded into "$colorstart"libvasile"$colorstop". Adjust it to suit your needs.
-
-	"$colorstart"--resetmode"$colorstop"
-		This option will allow you to reset the system state. It will remove whole portage tree, overlays and portage configuration files and reset the system profile. Usually
-		you will never want to call this option directly, unless you really really really know what are you doing. It is called automatically when switching to other states.
-
-		!!! WARNING !!! : Never never never leave the system in this state. You will no longer be able to install/remove/upgrade any packages untill you set the system profile,
-		get the portage tree, overlays and configure portage by hand. Or, you can always activate one of the three other supported system states.
-
-	"$colorstart"--binmode"$colorstop"
-		This option will allow you to change the system state to binmode. In this state portage will allways use only binary packages from the binhost. It will fetch a minimal
-		portage tree without any ebuilds in it, but only with portage profiles, metadata and eclass. It will also fetch overlay and portage configuration files, and will adjust
-		"$colorstart"make.conf"$colorstop" for binary only usage. This system state is for those who just meet with the power of Gentoo.
-
-		!!! WARNING !!! : Never never never modify or create any file in "$colorstart"/etc/portage/"$colorstop" in this state.
-
-	"$colorstart"--mixedmode"$colorstop"
-		This option will allow you to change the system state to mixedmode. In this state portage will prefer binary packages from the binhost over ebuilds from the portage tree.
-		It will fetch the full portage tree, the overlay and portage configuration files, and adjust "$colorstart"make.conf"$colorstop" for binary/ebuild usage. Usually you will find this system state
-		useful if you want to install a package not available in the binhost, you want to upgrade a package to a newer version from portage tree or if you wanna rebuild a package
-		with your own useflags.
-
-		!!! WARNING !!! : Never never never modify any file in "$colorstart"/etc/portage/"$colorstop" in this state. If you want to adjust useflags or keywords for a package, you can create a new file
-		e.g.: "$colorstart"100-my.package.use"$colorstop" in "$colorstart"/etc/portage/package.use/"$colorstop" or "$colorstart"100-my.package.keywords"$colorstop" in "$colorstart"/etc/portage/package.keywords/"$colorstop".
-
-	"$colorstart"--srcmode"$colorstop"
-		This option will allow you to change the system state to srcmode. In more clear terms, it will transform your Kogaion/Argent/Redcore system into pure Gentoo. Binary packages
-		from the binhost will be ignored, and you will only install packages building from portage tree using emerge. It will fetch the full portage tree, the overlay and portage
-		configuration files and adjust "$colorstart"make.conf"$colorstop" for ebuild only usage.
-
-		In this system state you can modify whatever you want in "$colorstart"/etc/portage/"$colorstop". You can adjust useflags, keywords, masks, build environment and rebuild the whole system to suit you.
-		You have the full power of Gentoo available only one command away!
-
-		!!! WARNING !!! : Only use this system state if you have a strong knowledge of Gentoo tools e.g.: "$colorstart"emerge, equery, layman, eix, qlist, useflags, keywords, masks"$colorstop".	"

+
+"$colorstart"DESCRIPTION"$colorstop"
+
+	Vasile is an acronym for ** Versatile Advanced Script for Iso and Latest Enchantments **
+
+"$colorstart"OPTIONS"$colorstop"
+	"$colorstart"--makepkg"$colorstop" ["$colorstart"package(s)"$colorstop"]
+		This option will allow you to build a package or multiple packages in an overlayfs mounted squashfs chroot jail.
+
+		It must be run in the folder where the squashfs chroot jail resides, or else it will fail to mount the squahfs chroot jail and build the package(s).
+
+		The squashfs chroot jail and the md5sum checksum file are hardcored into "$colorstart"libvasile"$colorstop", but you may want to change them to suit your needs.
+
+		You MUST provide package(s) to build as arguments, or else vasile will only mount the chroot jail
+
+		Examples :
+			"$colorstart"vasile --makepkg wine"$colorstop"
+			"$colorstart"vasile --makepkg wine playonlinux q4wine"$colorstop"
+
+		If the package(s) is/are already built, it will not build it/them again (unless newer version(s) is/are available), but install it/them into squahfs chroot jail
+
+		If the package(s) you want to build depends on any already built package(s) it will make use of it/them to satisfy the required dependencies.
+
+	"$colorstart"--makeiso"$colorstop"
+		This option will allow you to build a live iso image based on the squashfs chroot jail.
+
+		It must be run in the folder where the squashfs chroot jail resides, or else it will fail to rsync the contents of it and build the iso image.
+
+		It is not fully automatic, it will only rsync the contents of the squashfs chroot jail, chroot into it, and let you install packages you want into the iso image.
+		There are some predefined package sets available in "$colorstart"/etc/portage/sets"$colorstop". Adjust them to suit your needs.
+
+		It will ALLWAYS use package(s) built with "$colorstart"--makepkg"$colorstop" option. When you are happy with package selection, just exit the chroot environment and
+		the live filesystem will be compressed, live services will be autoenabled, live bootloader autoconfigured and in the end live iso image will be built. You will find
+		a list of predefined live services list hardcoded into "$colorstart"libvasile"$colorstop". Adjust it to suit your needs.
+
+	"$colorstart"--resetmode"$colorstop"
+		This option will allow you to reset the system state. It will remove whole portage tree, overlays and portage configuration files and reset the system profile. Usually
+		you will never want to call this option directly, unless you really really really know what are you doing. It is called automatically when switching to other states.
+
+		!!! WARNING !!! : Never never never leave the system in this state. You will no longer be able to install/remove/upgrade any packages untill you set the system profile,
+		get the portage tree, overlays and configure portage by hand. Or, you can always activate one of the three other supported system states.
+
+	"$colorstart"--binmode"$colorstop"
+		This option will allow you to change the system state to binmode. In this state portage will allways use only binary packages from the binhost. It will fetch a minimal
+		portage tree without any ebuilds in it, but only with portage profiles, metadata and eclass. It will also fetch overlay and portage configuration files, and will adjust
+		"$colorstart"make.conf"$colorstop" for binary only usage. This system state is for those who just meet with the power of Gentoo.
+
+		!!! WARNING !!! : Never never never modify or create any file in "$colorstart"/etc/portage/"$colorstop" in this state.
+
+	"$colorstart"--mixedmode"$colorstop"
+		This option will allow you to change the system state to mixedmode. In this state portage will prefer binary packages from the binhost over ebuilds from the portage tree.
+		It will fetch the full portage tree, the overlay and portage configuration files, and adjust "$colorstart"make.conf"$colorstop" for binary/ebuild usage. Usually you will find this system state
+		useful if you want to install a package not available in the binhost, you want to upgrade a package to a newer version from portage tree or if you wanna rebuild a package
+		with your own useflags.
+
+		!!! WARNING !!! : Never never never modify any file in "$colorstart"/etc/portage/"$colorstop" in this state. If you want to adjust useflags or keywords for a package, you can create a new file
+		e.g.: "$colorstart"100-my.package.use"$colorstop" in "$colorstart"/etc/portage/package.use/"$colorstop" or "$colorstart"100-my.package.keywords"$colorstop" in "$colorstart"/etc/portage/package.keywords/"$colorstop".
+
+	"$colorstart"--srcmode"$colorstop"
+		This option will allow you to change the system state to srcmode. In more clear terms, it will transform your Kogaion/Argent/Redcore system into pure Gentoo. Binary packages
+		from the binhost will be ignored, and you will only install packages building from portage tree using emerge. It will fetch the full portage tree, the overlay and portage
+		configuration files and adjust "$colorstart"make.conf"$colorstop" for ebuild only usage.
+
+		In this system state you can modify whatever you want in "$colorstart"/etc/portage/"$colorstop". You can adjust useflags, keywords, masks, build environment and rebuild the whole system to suit you.
+		You have the full power of Gentoo available only one command away!
+
+		!!! WARNING !!! : Only use this system state if you have a strong knowledge of Gentoo tools e.g.: "$colorstart"emerge, equery, layman, eix, qlist, useflags, keywords, masks"$colorstop".	"
