# cli_getThemeName.sh -- This function manipulates the current

# absolute path to extract the theme name from it. If there is no

# theme in the path, this function returns an empty string.

#

# Theme names are stored in directories immediatly under

# Themes/Motifs/ directory and and can be named using letters and

# numbers. When rendering themes under branches/ directory structure,

# theme names are also built using the branch numeration the theme is

# being rendered for.

#

# Branch enumeration start at number one and increment one unit each

# time a new branch is created from the same trunk development line.

# If a branch is created from another brach then a new directory is

# created inside the source branch, using the same enumeration schema.

# So, we may end up with paths like

# branches/.../Themes/Motifs/Flame/1,

# branches/.../Themes/Motifs/Flame/1/1,

# branches/.../Themes/Motifs/Flame/1/2,

# branches/.../Themes/Motifs/Flame/2,

# branches/.../Themes/Motifs/Flame/2/1, and so on.  In all previous

# examples the theme name holds the branch enumeration schema too.
