28 |

29 |
+# The bzr.eclass provides functions to fetch and unpack sources from |
30 |
+# repositories of the Bazaar distributed version control system. |
31 |
+# The eclass was originally derived from git.eclass. |
32 |
+# |
33 |
+# Note: Just set EBZR_REPO_URI to the URI of the branch and src_unpack() |
34 |
+# of this eclass will export the branch to ${WORKDIR}/${P}. |

102 |

103 |
+# The repository URI for the source package. |
104 |
+# |
105 |

112 |
+# variable is set, the initial branch will be cloned from the location |
113 |
+# specified, followed by a pull from ${EBZR_REPO_URI}. This is intended |
114 |
+# for special cases, e.g. when download from the original repository is |

+# |

+# Normally, this variable needs not be set. |

+# in the ${EBZR_STORE_DIR}/${EBZR_PROJECT} directory. |
123 |

128 |
+ |
129 |
+# @ECLASS-VARIABLE: EBZR_BRANCH |
130 |
+# @DEFAULT_UNSET |
131 |
+# @DESCRIPTION: |
132 |
+# The directory where to store the branch within a shared repository, |
133 |
+# relative to ${EBZR_STORE_DIR}/${EBZR_PROJECT}. |
134 |
+# |
135 |
+# This variable should be set if there are several live ebuilds for |
136 |
+# different branches of the same upstream project. The branches can |
137 |
+# then share the same repository in EBZR_PROJECT, which will save both |
138 |
+# data traffic volume and disk space. |
139 |
+# |
140 |
+# If there is only a live ebuild for one single branch, EBZR_BRANCH |
141 |
+# needs not be set. In this case, the branch will be stored in a |

+# stand-alone repository directly in EBZR_PROJECT. |

153 |

154 |
+# by users. |

159 |
+# @DESCRIPTION: |
160 |
+# Set this variable to a custom umask. This is intended to be set by |
161 |
+# users. By setting this to something like 002, it can make life easier |
162 |
+# for people who do development as non-root (but are in the portage |
163 |
+# group), and then switch over to building with FEATURES=userpriv. |
164 |
+# Or vice-versa. Shouldn't be a security issue here as anyone who has |
