"I often find interesting source code repositories online that I want to grep"
" for some pattern but I can't, because either:"
msgstr ""

msgid ""
"the repository is on [cgit](https://git.zx2c4.com/cgit/) or a similar code "
"repository that doesn't allow search in files, or;"
msgstr ""

msgid ""
"the search function is really bad, and doesn't allow me to use regular "
"expressions for searching patterns in the code."
msgstr ""

msgid ""
"Here's a simple script that allows you to overcome that problem easily:"
msgstr ""

msgid ""
"It is a wrapper around `git grep` that downloads the repository when "
"missing. Save in a file called `git-search`, make the file executable and "
"add it to your path."

msgid "*line 33*:"

msgid "*lines 34~37*:"
