12 $ME: Manage SLiM themes
14 Usage: $ME OPTION [NAME]
16 Options:
17 -h Display this short help and exit
18 -l List available themes (comma separated)
19 -g Get the name of current theme (note, it can be comma separated list)
20 -s NAME Set NAME theme as current; name of previous theme will be stored
21 (note, you can set comma separated list for random theme behavior)
22 -f NAME Forget about NAME theme and return to previous used theme
23 -V Display information about $ME version
24 -t Translate current theme\'s strings according to global LANG value
25 (note, its done auto when -s processed)
26 -T LANG Same as above, but use specified language
28 Set option works like stack: you can "set" theme several times (every time you
29 install new SLiM theme). Use "forget" option at every theme uninstall to revert
30 to previous theme, if it was current.
