.TH DH_MAKESHLIBS 1
.SH NAME
dh_makeshlibs \- automatically create shlibs file
.SH SYNOPSIS
.B dh_makeshlibs
.I "[-v] [-a] [-i] [-mmajor] [-Ptmpdir] [-ppackage] [-mmajor] [-V [dependancies]]"
.SH "DESCRIPTION"
dh_makeshlibs is a debhelper program that automatically scans for shared
libraries, and generates a shlibs file for the libraries it finds.
.P
For this program to work, you cannot have already installed a DEBIAN/shlibs
file. If such a file exits, the program will exit with an error.
.SH OPTIONS
.TP
.B \-v
Verbose mode; show all commands that modify the package build directory.
.TP
.B \-a
Generate shlibs files for all architecture dependent packages.
.TP
.B \-i
Generate shlibs files for all architecture independent packages.
.TP
.B \-ppackage
Generate shlibs file for the package named "package".
.TP
.B \-Ptmpdir
Use "tmpdir" for package build directory. 
.TP
.B \-mmajor
Instead of trying to guess the major number of the library from the filename
of the library, use the major number specified after the -m parameter.
.TP
.B \-V [dependancies]
By default, the shlibs file generated by this program does not make packages
depend on any particular version of the package containing the shared
library. It may be necessary for you to add some version dependancy
information to the shlibs file. If -V is specified with no dependancy
information, the current version of the package is plugged into a dependancy
that looks like "packagename (>= packageversion)". If -V is specified with
parameters, the parameters can be used to specify the exact dependancy
information needed (be sure to include the package name).
.SH EXAMPLES
.TP
.B dh_makeshlibs
Assuming this is a package named libfoobar1, generates a shlibs file that
looks something like:
  libfoobar 1 libfoobar1
.TP
.B dh_makeshlibs \-V
Assuming the current version of the package is 1.0-3, generates a shlibs
file that looks something like:
  libfoobar 1 libfoobar1 (>= 1.0-3)
.TP
.B dh_makeshlibs \-V "libfoobar1 (>= 1.0)"
Generates a shlibs file that looks something like:
  libfoobar 1 libfoobar1 (>= 1.0)
.SH NOTES
The
.B \-a
.B \-i
and
.B \-p
arguments are cumulative. If none are specified, then all packages listed in
the control file will be effected.
.SH ENVIRONMENT
.TP
.I DH_VERBOSE
Enables verbose mode

.SH BUGS
Due to limitations in
.BR getopt (1)
, I had to fudge a bit on how the -V parameter really works. When -V is
specified, it's really examining the rest of the command line for any text
that isn't a switch, and using that for the dependancy information. This
means that the -V switch and any dependancy parameters should come last on
the command line.
.P
There is no guarantee that the program will get the shlibs file right. For
example, it may not correctly guess the major number of your package. In
cases like these (and perhaps in general, just to be safe), it is better to
create a debian/shlibs file by hand, or force it to use the correct major
number by specifying the -m parameter.
.P
This is a "do what I Mean" type program - you have been warned!
