In order to add a menu entry I created the following files (used/tested on Linux Mint 18/18.1).
The install-script (install.sh) expects a subfolder "freemind" containing the extracted freemind-files, e. g. freemind/freemind.sh
also an icon-file "freemind.ico" is expected to be in that folder, which is something that at least was missing from the distributed files at the time I created this solution.

Feel free to adapt.

install.sh:

#!/usr/bin/env sh
cp -a freemind /opt/.
cp freemind.desktop /usr/share/applications/.

freemind.desktop:

[Desktop Entry]
Name=FreeMind
Comment=FreeMind Mindmapping Software
GenericName=freemind-1.0.1
Exec=/opt/freemind/freemind.sh
Icon=/opt/freemind/freemind.ico
Type=Application
Terminal=false
StartupNotify=true
Categories=Multimedia;Utility;

HTH,

please add some mechanism to check the validity of the encryption key. And add the repository only after successfull check of the key.
bash-solution:

# KEY_ID and FINGERPRINT taken from http://eric.lavar.de/comp/linux/debian/
KEY_ID='869D2871'
FINGERPRINT='98FB 95CD 6C40 4DF7 E758 601D 27CD 3F36 869D 2871'

function _installed_fingerprint() {
	key_id=$1
	apt-key fingerprint $key_id \
	| /bin/grep fingerprint \
	| sed 's/.* = //' \
	| sed 's/  / /' # fixing the double-space-character if apt-key output
}

function _isKeyValid() {
	expected=$FINGERPRINT
	installed=$(_installed_fingerprint $KEY_ID)
	
	if [ "$expected" == "$installed" ];
	then
		echo 1
	else 
		echo 0
	fi
}

# add some test after installing the key, like:
if [ $(_isKeyValid) -eq 1 ]; then
	echo "add repository"
	add_repository
else 
	echo "ERROR: could not add repository"
	echo "       comparison of keys's fingerprints failed"
	installed_fingerprint=$(_installed_fingerprint $KEY_ID);
	echo "installed: $installed_fingerprint"
	echo "expected:  $FINGERPRINT"
	exit 1
fi

Note: recently I added a docker repository with this function, the commandline-program "add-apt-repository" seems more robust, than catting into a file.

function add_repository() {
	sudo add-apt-repository \
		"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
		$UBUNTU_PARENT \
		stable"
}

I have tried out your "please add some mechanism to check ..." script. I get this:

Warning: apt-key output should not be parsed (stdout is not a terminal)
ERROR: could not add repository
       comparison of keys's fingerprints failed

I think there's something wrong with Eric Lavarde's key. expired or something maybe? or his repo isn't signed with it (anymore)?

The following signatures were invalid: 98FB95CD6C404DF7E758601D27CD3F36869D2871

sort of calls this out.
