99 Usage: nd-aptenable [options]
101 Enables NeuroDebian repository for the current Debian or Ubuntu release.
105 -r, --release=RELEASE
106 Name of the Debian/Ubuntu release to be used. If not specified,
107 it is deduced from the apt-cache policy output, by taking repository
108 of Debian or Ubuntu origin with highest priority.
110 -f, --flavor=full|libre
111 Which flavor of the repository should be enabled:
112 libre -- Only main component, containing only DFSG-compliant content.
113 full -- Includes main, contrib, and non-free.
114 If not specified -- deduced from the output of apt-cache policy
116 -c, --components=c1,c2,c3
117 Comma separated list of components to enable among:
118 software -- primary software repository
119 data -- data packages
120 devel -- "overlay" of development versions (like Debians' "experimental").
121 Not sufficient on its own and available only from the main site
122 If not specified -- "software,data"
124 -m, --mirror=NAME|URL
125 Which mirror to use. Could be a mirror code-name (as specified in
126 /etc/neurodebian/neurodebian.cfg), or a URL.
129 If apt file already present, it would not be overriden (by default).
130 Use this option to overwrite.
133 Which suffix to add to the apt file, in case you are trying to enable
134 multiple repositories
136 --sources, --no-sources
137 Either to enable deb-src lines. If none specified -- would be enabled if
138 sources for a core package (apt) are available.
141 Do not perform any changes -- generated configurations and commands will
142 simply be printed to stdout
145 If found absent, all necessary tools (wget, netselect) if available will
149 Enable additional progress messages. Could be used multiple times
152 Make operation quiet -- only error messages would be output
155 Print short description, usage summary and option list.
158 Print version information and exit.
162 non-0 exit status in case of error. Error exit code would depend
163 on which command has failed
167 - Enable software and data components from the optimal (according to
168 netselect) mirror. Some information about progress will be printed
172 - Quietly enable -devel repository for the current release, and place apt
173 configuration into /etc/apt/sources.list.d/neurodebian.sources-devel.list
175 nd-aptenable -q --suffix=-devel -c devel
177 - Force sid distribution, all the components, from the Japan mirror:
