Unoconv will depend on the core library from libreoffice for conversion of different documents but we do not have to install all of the libreoffice package.
By running apt-cache depends unoconv
we can see the following dependencies:
unoconv
Depends: python
Depends: python-uno
We will also need python-uno with the following dependencies:
python-uno
Depends: libreoffice-core
Depends: python2.7
Depends: python
Depends: libc6
Depends: libgcc1
Depends: libpython2.7
Depends: libstdc++6
Depends: uno-libs3
Depends: ure
Thus in addition to Python and C-libraries the following additional packages from the libreoffice suite (installed size on amd64 in brackets) are needed:
- libreoffice-core (117,412.0 kB)
- uno-libs3 (1,796.0 kB)
- ure (6,775.0 kB)
Hence in terms of size roughly half of the libreoffice package will be installed with unovonv.
