[Solar-general] divisor de nombres de paquetes

lentamente continuo avanzando con sumpack

esto parece tonto, pero es util

es un script , bajo el nombre de upackname que separa nombres de
paquetes en sus partes
(para lo que hago necesito solo dos: nombre y version, pero no es
dificil separar mas en este contexto: release, etc)

si alguien conoce algo mejor, sacarle errores, o como mejorarlo o
darle mas capacidades, gracias

     #The name of the package itself (not the filename, just the name
of the package) can contain lowercase letters, numbers, and the "-"
and "+" characters.
     #debian_revision

     #This part of the version number specifies the version of the
Debian package based on the upstream version.
     #It may contain only alphanumerics and the characters + . ~
(plus, full stop, tilde) and is compared in the same way as the
upstream_version is.
     #It is optional; if it isn't present then the upstream_version
may not contain a hyphen.
     #This format represents the case where a piece of software was
written specifically to be turned into a Debian package,
     #and so there is only one "debianisation" of it and therefore no
revision indication is required.
     #It is conventional to restart the debian_revision at 1 each time
the upstream_version is increased.
     #The package management system will break the version number
apart at the last hyphen in the string
     #(if there is one) to determine the upstream_version and
debian_revision. The absence of a debian_revision is equivalent to a
debian_revision of 0

     #The VVV component is the version number specified by the upstream
     #developer. There are no standards in place here, so the version number
     #may have formats as different as "19990513" and "1.3.8pre1".

     #The RRR component is the Debian revision number, and is specified by
     #the Debian developer (or an individual user if he chooses to build the
     #package himself). This number corresponds to the revision level of the
     #Debian package, thus, a new revision level usually signifies changes
     #in the Debian Makefile (debian/rules), the Debian control file
     #(debian/control), the installation or removal scripts (debian/p*), or
     #in the configuration files used with the package.
     #The AAA component identifies the processor for which the package was
     #built. This is commonly i386, which refers to chips compatible to
     #Intel's 386 or later versions. For other possibilities review Debian's
     #FTP directory structure at What are all those directories at the
     #Debian FTP archives?, Section 6.7. For details, see the description of
     #"Debian architecture" in the manual page dpkg-architecture(1).
