* Merge from Debian unstable (LP: #978012), remainging changes:
- debian/control.in:
Build-depend on gettext:any instead of on gettext for (cross-building)
Drop build dependency on dc, which hasn't been needed for some time.
Update maintainer field.
- debian/rules:
Block pkg-create-dbgsym from operating on this package.
Build without dietlibc-dev, which is in universe
- debian/control:
Regenerate with ./debian/rules debian/control

* pfsck --- A generic, parallelizing front-end for the fsck program.
3
* It will automatically try to run fsck programs in parallel if the
4
* devices are on separate spindles. It is based on the same ideas as
5
* the generic front end for fsck by David Engel and Fred van Kempen,
6
* but it has been completely rewritten from scratch to support
7
* parallel execution.
8
*
9
* Written by Theodore Ts'o, <tytso@mit.edu>

*
11
* Miquel van Smoorenburg (miquels@drinkel.ow.org) 20-Oct-1994:
12
* o Changed -t fstype to behave like with mount when -A (all file
13
* systems) or -M (like mount) is specified.
14
* o fsck looks if it can find the fsck.type program to decide
15
* if it should ignore the fs type. This way more fsck programs
16
* can be added without changing this front-end.
17
* o -R flag skip root file system.
