These files are here rather than in a proper repository solely because I don't know yet what I am doing. If there appears to be interest in my program within the Linux community, I will try to learn some more and do things properly. I created the .deb file using "dpkg -b" under Linux Mint 12 running GNOME 3 and gnome-shell on a 32-bit laptop.
The executables for this software install into /u/local/bin. So far as I know, the installer will create this directory if it does not exist. For the software to work properly, you must add /u/local/bin to $PATH. You can do this by issuing the command "export PATH=$PATH:/u/local/bin" from the command line or by putting a similar line in your .bashrc file.
On my machine, I was able to install the software by double-clicking on the .deb file and entering my password. According to the Ubuntu documentation, I could have instead issued the command "sudo dpkg -i emmesmail_0.4.0_386.deb" after "cd"ing to the directory containing the .deb file.
According to that same documentation, the program may be removed using "sudo dpkg -r emmesmail". I removed it with "sudo apt-get remove emmesmail".
Bugs:
32-bit .deb for Debian/Ubuntu/Linux Mint
32-bit .rpm for Fedora/Red Hat/CentOS
The software is issued under the GNU GPL. For those who need it, the source tarball is here. The software may be compiled by issuing the command "make", and installed with "make install". Aditionally, a .deb install file may be created with the command "make deb".
