A collection of PDF command line tools and wrappers for Linux written in Bash Shell script. These are generally speaking convenience tools so one does not have to remember very long and cryptic options and switches.
The heavy lifting is done by backend tools such as pdftk, ghostscript and the poppler utils are used.
The scripts are meant to be installed in a users' home directory. To do this
quickly the Makefile in the root of the repository has a target called
user_install.
$ make user_install
Install pdftools under /home/<user>/bin
-> Installing bin/img2pdf to /home/<user>/bin/img2pdf
-> Installing bin/ocrpdf to /home/<user>/bin/ocrpdf
-> Installing bin/pdf2pdfa to /home/<user>/bin/pdf2pdfa
